Topcat's Other Misc Weird Build Thread

[Topcat]

nForce 650i... now that's a interesting challenge. Weren't those known to have FSB holes?

FSB holes>? What's that?

I found a pair of GTX 285's for peanuts....so I guess that cat is out of the bag!!

nForce 650i... now that's a interesting challenge. Weren't those known to have FSB holes?

[Topcat]

Next build I'm kind of excited about. It was a drop off for recycling. Dell XPS 630i. These are slightly on the rare side....but this one was a little more unusual; as it's the red-faced one and also the liquid cooled version as well....I didn't even know the liquid cooler was an option with them. The GPU was missing and the PSU has bad caps....so it didn't work. Not sure what GPU it had....there were a quite a few GPU options with these, the best one being a GTX285; which probably won't be hard to find.

Testing the motherboard in the oven:



Don't pay any attention to the CPU. I pulled the 9650 out so I could use it elsewhere. I just stuck something in here to test the board....as the first test is 8gb RAM support. It should support 8gb....but lots of internet scuttlebutt says it won't (no POST and beeps errors)....well, not sure what others ran into, but 8gb ran fine for me. I'll let memtest run for a while to be sure, but thus far no issues!!





The liquid cooler.....



Next will be a 5400-series Xeon test. I don't have any spares laying around that are modified for a LGA775, so I've got one coming. Going for an X5470 3.33GHz quad core. Wasn't going to waste my time on a 5450; as that's the same as the C2Q 9650 that I just pulled out.....no gains at all....so if it's going to be done, it's going to be done for some gain....but so far so good!

[Topcat]

The final results of the above Coolermaster setup....

I won't go into all the gore....but here's the power distribution & switching controller for the lighting that allows the front panel on/off switch to be used. The wiring & connectors were harvested from junk TV's.



Enclosed in a black box under the drive trays. The shell was an old power brick that I stripped out and repurposed.




Still as difficult as ever to photograph....





Lights off by the front panel switch....



Lights on....



Ok, not really a big deal....but this was pretty much an orphan system I had no use for....I snatched what I wanted from it....so why not have a little fun!!

[Topcat]

This was the leftover system after I snatched the Tableau Forensic bridge out of it for my data recovery station......so now to have some fun with it...............excuse the wire mess...it's all cobbled together in test form powered by my bench supply.

[Topcat]

Finished up the Gateway server sleeper today. Not as much of a sleeper as I wanted it to be, it was doomed to period-specific hardware because of the SCA backplane....but it turned out pretty darn nice IMO.

Tied up the wiring.....



Buttoned up and XP installed...





Only one hiccup, the Adaptec 2120S RAID controller ended up being bad. Kept getting timeout errors and drives dropping out of the array. Replaced drives, thinking they were the culprits, but the issues continued on all drives on all bays. I pulled that and stuck an Adaptec 29160 64-bit card in its place with a single Cheetah 147gb 15K U160. No more issues. The crystaldisk results are pretty good for hardware of this era, this is where the 15,000 RPM really shines.

Specs:

Supermicro P4DCE+
2x Prestonia core Xeons @ 3GHz
2GB RDRAM
ATI X1600 Pro 512mb
Adaptec 29160 64-bit SCSI controller
All housed in a Gateway 2000 930 chassis

Q3A played silky smooth in 1600x1200 with everything on.

We interrupt your regularly scheduled build to show off Topcat's completely pimped out Precision T7910. This was a freebie from a local resort that survived being hammered because the grunts couldn't find the HDD's, they mistook the optical for a 'hard drive' and beat that with a hammer....no, I'm not kidding!!

Anyway... It had 64gb RAM spread across 8 of its 16 slots and 2x Xeon E5-2690 v4 CPU's and a big turd of a NVS 310 GPU. I didn't change the CPU's, they are a decent balance of clock speed and core count; 28 cores / 56 threads!! Wowza!! I did however up the RAM to 128GB with matching modules to what was in it....and after some research upgraded the GPU's to a pair of Quadro K5200 8gb cards. This system does support SLI, but for quadro's only....no GTX / RTX's will do it.... Licensing thing from nvidia....workstation versus game....so here we are!!

I didn't dwell too much on the gore, but here's a few. Testing some things and RAM added.



SAS card pulled. The plastic pegs that hold the heatsink on broke immediately. That processor on the card gets miserably hot. Had to replace the pegs and the thermal grease.



Pulled the SAS card for this: A Dell NVMe adapter with 2x slots inside. I added a 1TB M.2 for OS / boot.



Next up, I added the 4 bay 2.5" SAS cage to go along with the existing 4 bay 3.5" cage below it. The 2.5" cage is an option.



These fans were part of the kit.





SAS card replaced under the NVMe adapter and connected to the SAS cages. These cages are empty for now, but leaves lots of room for expansion for more drives.



Wiring tidied up.



Note the crack on the slimline optical tray. Yes, it survived the hammering. The drive was destroyed, but it's a common/standard SATA slimline. I have boxes full of them. I had to take a heatgun to it to reshape it, but it does latch into place. Yes, this is what they beat up thinking it was a 'hard drive'. I'm just glad they stopped there. Most of the other systems I got from them were pulverized beyond any form of salvage or reuse.



...and there you have it!! A totally pimp-a-licious Precision T7910!! The only thing I couldn't find were the liquid coolers that were also optional for these. Very rare apparently.





System specs:

Precision T7910
2x Xeon E5-2690 v4 @ 2.6GHz x14 cores per CPU. 28 cores 56 threads
128GB ECC DDR4
2x Quadro K5200 8GB GPU's in SLI; 16gb dedicated video RAM
1TB M.2 boot storage
12G SAS adapter w/ 8 bays for storage expansion
Win10 Enterprise

This would bring a nice price on ebay....but I'll try to rehome it locally.

[Topcat]

No, I haven't forgotten about this build....I've just been busy with other crap... I broke down and grabbed a pair of 3GHz CPU's for it, they're not here yet though....but that won't stop me from starting to button this up....but there were a few things that had to be done first....one thing at a time though...

Shiny & clean!



SCA HDD's selected. Pair of 146gb 15,000 RPM.




This project wasn't without a casualty. Little plastic latch had broken. This would cause the face to not stay on. Nothing some JB weld couldn't handle.



Good as new!




Now for the front panel connectors. The original was a proprietary setup with a ribbon.



Had to sever some traces, as they had all the LED's sharing a common, the new motherboard does not share this, and won't work right if tried (been there)....but here we are!





Back in the case.



Face back on and SCA trays inserted.



Next up is the power supply I had to add an 8-pin EPS connector to use this supply with this board. This was an interestingly designed power supply. ALl rectification is done internally along with standby voltages. The modules only provide the usable power for the PC. This PSU will power up, have standby, and run the fans at low speed with no modules inserted.



I removed the I2C cabling, as it interfaces with the original motherboard for the front panel LED's, The new board won't interface with it, so to save clutter, I just removed it.



Added the 8-pin plug. I had enough ground through holes for all 4 wires, so each wire got its own. The +12, I only had 2 free through holes....so I had to doublejack them. Not a big deal, this board pulls very little from the +12v rail anyway....but it won't run without this connector installed.



Done.



Tested. Works.



Installing. Pay no attention to the poor cable management at this point....





That's all until the CPU's get here....Stuck a magnificent period-specific GPU in this one.

[Topcat]

Especially as I've been getting interested into VP6s since Epictronic and BigBadBioligist's VP6 research.

Weird you say this. I built 3 custom polymer VP6's many many many years ago (like back when the VP6 was still usable in the real world) and sold them to an individual that had some specific use; and they agreed to return them to me when they finished with them and took them out of service. They did return two of them several years ago, one is still MIA. They never would tell me what they were being used for; I did ask. I still have them.

Back to this build......

Today was the disassembly stage.








The backplane. If I really wanted to use modern drives in this, I could simply remove the backplane and just use internal cables with the drives. The trays latch in the front, so the drives would stay put.....but I think I'm just liking the revived old SCSI instead. old world SCSI gear is something else that's beginning to vanish. Controllers & cables are plentiful, but good drives are rapidly drying up; both HDD and ODD.



Motherboard disconnected.




Board & PSU out....along with the SCA backplane.



Motherboard tray.



Case shelled out. All parts need to be cleaned.



All the parts.



Overall, this is a fabulously made case, heavy & thick old iron.

One thing I'm still contemplating is ordering a couple 3GHz Prestonia CPU's....they're about 90 bucks for a pair.....but only one guy has them, and they're not easy to come by anymore. They're the fastest CPU the board could take; 400FSB only. The board has a pair of 2.2GHz that came with it. I'll ponder that one, as I don't have a lot in this....just the memory I bought. I bought the motherboard in a lot of two identical. I sold the other board after testing it for what I had in both, so that was a wash.

Anyway, to be continued.

[Dan81]

I'll PM you next week about them. Still gotta find what would the prices to ship it outside US be and get my friend to help charging my card. Especially as I've been getting interested into VP6s since Epictronic and BigBadBioligist's VP6 research.

[Topcat]

I've been wanting to do something 486 based in quite a long time and was always waiting for a proper mobo.

Should have said something....I have a Micronics 486DX4@100 here I have zero plans for...could toss a couple VP6 fixer-uppers in with it....


Anyway, for today's magic, the beginning stages of this monster Gateway server system. I am not going to reuse the original board, while it's a dual Tualatin, it's otherwise a complete turd....as a server, this thing is useless for anything, so the goal is more of a minor sleeper/gamer/era-specific workstation setup. First step is board selection. The front-runner is this Supermicro P4DCE+; dual skt603 Prestonia Xeon board. One of the first; 860 chipset and RDRAM. The prerequisites are really only SCSI for the SCA cage. I also had to make sure it'll pair with the PSU specs, the power supply in this case has a pretty weaksauce 12v rail, but the 5v and 3.3v are beasts! This board will definitely play nice with this PSU after a good run in the oven. There's one more model board on ebay of similar era I am considering, but it's live bidding and already bid up more than I really want to spend....so I'm probably going to pass on that one....so here we are!!

The board doesn't have onboard SCSI, so I just added a card with RAID functions.



Of course in testing I was having some issues with the controller.... Anytime that happens, the first thing I check is firmwares...and sure enough, ancient version....updated!



Problems went away.

So here's the system core so far:






Now a closer look at the case. A butt shot.....






Amazingly enough all the caddies were there. There was one drive present; a 36gb 10k Cheetah, all the rest of the trays had their dummy drives in them. The drive was blank, someone wiped it.





Inside:





The SCA backplane. Unlike newer stuff that was made during the transition from SCSI to SAS, there's no interchangeable SAS/SATA backplane, this is too old...which is why it's doomed to SCSI.



An eATX board will fit this case with no modifications (atleast that I'm aware of as of now), but there's some electrical mods that will need to be made for the front panel connections and the PSU. The ATX connector is standard pinning and voltages, but there's no 4/8-pin EPS plugs, so they'll have to be added. I could also run any ATX PSU in this with some minor modification; would just have to make a frame/bracket for it....but I'd like to keep that portion original, which is why anything really modern was ruled out (weak +12v rail).

More to come.

[Dan81]

Speak of being lucky. Same seller I ordered the 694D just packed and will send a VLB based 486 pack.

ID'd so far:

- mobo is a Aquarius Systems MB-4D33NR w/ actual socket 3. Unknown CPU though I suspect either a 486DX-50 or a DX2-66.
- GPU is a VLB Trident TVGA9200
- has a VLB IDE controller
- 2x NICs (!!) - one is a UMC card, the other is a 3com

Will likely make a nice 95, 3.1 and DOS machine - I've been wanting to do something 486 based in quite a long time and was always waiting for a proper mobo.

[Dan81]

At first I was leaning towards the BP6 too but figured the 694D would make more of a killer 370 build with that Tesseract. Gotta give Deepcool credit, they made one hell of a case. That, and I was feeling really uncomfortable modding the sockets on the BP6, given these are as rare as hell where I live.

AGP4x, VIA chipset and the 4 SDR slots make for quite a good expansion horizon. Might drop some really mean Socket 462 copper coolers - assuming I can get their clips swapped, as the 694D (and I suspect the VP6 would've had that issue too but idk) Pro seems to have the well known clearance issue that buggers me to no end on SS7 and 370 boards.

Might have to figure what GPU to go for - it's gotta be something DX9 or early DX10, but also has to be a fairly good performer. So far a few candidates to it would be a HD3450 AGP (made by ASUS), a Gecube 9600 Pro and a 3D Prophet 9700 Pro.
Also got a single socket "plan B" board - the well known K7S5A, recapped with Rubies and a few polys off scrap first gen 360s without the HDMI ports.

[Topcat]

Nice. I have an nearly total opposite build in mind to build and will likely pick up one of those good ole' trusty DeepCool Tesseract cases.

Wanna pick a guess what it'll be?

It's gotta be that BP6 or that 694D you've got coming.

This one was wrapped up over the weekend. Is it one for Topcat's Weird Build Hall of Fame? No....but turned out good none the less.....

The motherboard has been chosen....and it was a tough call, there were several very worthy contenders, but this one was the best fit IMO.



It's testing in the oven, and also analyzing power usage to see what PSU would be best suited for it. It's too heavy on the 12v rail to use the original.



The mystery board sign in please..... Asus K8N-DL ebay rescue from about a year ago.




There were several parameters that had to be met to maintain front panel function; optical drives and the zip drive. This meant I needed an IDE / SATA hybrid; with 2 40-pin IDE channels, that this board has....and a SATA port for a SSD so it's not agonizingly slow. That was the deciding factor in the end with the other front-runner boards.

Next up is to depin & remove the proprietary front panel LED plug.




Just like that!!



USB ports and front panel cabling back in the case.



Now for the motherboard standoffs. The brass ones came off the original board; 6 all together....but this board needed 9....and I didn't have any more of the gateway Brass ones....but fear not, the plastic ones fit the config just fine as you can see.



...and in the board goes!!






Now here's why this board was such a marvelous fit in this case..... Installed the HDD cage and note how the notch in the board so elegantly wraps the HDD cage. That couldn't have been planned any better!! A couple of the motherboard candidates would have required deletion of the HDD cage.





Now for those unsightly IDE ribbons..... I tidied them up the best I could.



Now for the power supply. This is a Seasonic 500W with fresh caps and a hefty 12v rail. Perfect for this system




SSD in an adapter tray.


Buttoning up.



Installed Win7 on this.


...and a little Q3A




System specs as follows:

Asus K8N-DL motherboard
2x dualcore Opteron 280's @ 2.4GHz
6GB DDR1-3200 ECC - Rumor has it, it can unofficially run 12gb...but I don't have the RAM to try it
Nvidia 9800GT Momaka's favorite single-slotter
120gb Kingston SSD

[Dan81]

I just dropped a Celeron 433 in it w/ a old cheap PPGA-only slotket and it'll end up with that up on sale. Apparently the SL2HC is unlocked, something I have been looking for quite some time, so I don't mind parting ways with a Mendocino 433. (I have a 400, 533, 500 and IIRC I think a 466 as well but not sure. Didn't count the 333s in the BP6 as they go together.)

Slightly surprised it supports Mendocinos though - IIRC TRW shows only Covington support for the 6DLX.

[Topcat]

I was seriously laughing at the names associated with that board!!

If you want to run it @ 533, get a cheap slotket and run a 533MHz medocino celeron in it; they can be had for peanuts. Any slotket can run a medocino. The fastest P2 it could run would be a 333....and a mendocino would spank it as it is, if for no other reason the full speed L2 cache. Being a LX chipset, don't waste your time trying to overclock....it won't be stable. You might get 75 to run fair with the right CPU, but it's a lot like the BX @ 133, it's always going to be quirky no matter what you do.

[Dan81]

You sure it wasn't the HDD at fault for WinME being slow? I used it recently on a 500MHz Katmai build with a GF2 Pro/GTS w/ the same amount of RAM and it was pretty speedy.

Onto funky stuff... dug this Baby-AT Tomato 6DLX and what I suspect (I am not fully sure) is a unlocked 266MHz P2, SL2HC. It'll clock to 333 just fine but I haven't pushed it past that. The BIOS is absolutely packed with features, and CPU speed is set thru BIOS - no jumpers whatsoever.

I'll prolly dump the 266 into my BE6-II and see if it can OC. Zida reports a max setting of 533 - but I have some quite high doubts it can jump that high....

[Topcat]

You did some very nice surgery work on this computer case and it is looking very nice I keep getting inspired by your handwork
I have one question for you what type of tool did you use for this surgery that you did on this computer case
One more question how did you determine where to cut the opening so that the motherboard would fit on the stand-offs would line up and PIC slots would also line up correctly

It's really not that hard. On most I do this to, they were the 'standard' IO of sorts, meaning there are always fixed positions; such as KB/MS, parallel, and serial ports. I'll use a removable IO shield of the same config and simply line up the port openings. I'll then trace the outer perimeter of the IO shield with a sharpie. Then measure from the outer edge inboard to the outer lip where it would latch into the case and them mark that off on the case....then tape off those marks and cut. I use a pneumatic die grinder on this one, it's a thicker steel case. A dremel with a reinforced cutoff wheel will also work, you just have to move slower & be a little more patient with it. Always cut on the waste side of the line/tape....if the opening is slightly small, nothing a file can't fix. Always make sure to file the edges anyway to remove burrs and sharp edges.

Now an non-standard IO shield like the Aurora R7 I removed was a bit more complicated, as the IO ports on this one were not following any kind of standard; thus no reference points. This one required a lot of very careful measuring......
