I decided to see what kind of "sleeper" build I could do on the Emachines T3104 from cheep/free thread with the "random junk" I had laying around (with the exception of a SATA to IDE adaptor I bought to make the original Emachines optical drive to work).
Before:
Specs:
Motherboard: FIC K8M-800M
CPU: AMD Sempron 3100+
RAM: 512MB DDR-400 (2x256MB)
GPU: Integrated VIA Unichrome Pro
PSU: HiPro HP-P3527F3 300W
HDD: None/removed (case sticker indicates it originally had a 100GB IDE HDD)
ODD: Lite-On DVD-ROM/CD-RW Combo
OS: none (no HDD), Windows XP Home Key

After:
Specs:
Motherboard: ASUS H81M-C
CPU: Intel I5-4690
RAM: 8GB DDR3-1600 (2X4GB)
GPU: AMD Radeon RX470
PSU: SeaSonic M12-II 520W
SDD: Timetec 256GB SSD
HDD: 1TB Western Digital Green
ODD: Lite-On DVD-ROM/CD-RW Combo
OS: Windows 10 Pro


At least from the front and sides it could still easily pass for an old Emachines, though the back has some giveaways with the PSU and dual-bay GPU:



Benchmarks:




Overall, it is about on par with a modern mid-range laptop, but that is still a big improvement from the basically unusable (unless you want a low-end XP system for some reason) to relatively competent.
