Thats okay, you'll get better with practicing.
It's easier if you heat only one leg at a time and wiggle the capacitor out. I've included some pictures below of this "wiggle" method (MS Pain style ).

Basically you go through steps 1 and 2 until the capacitor comes out.

Could be the Bestec if the 12v goes too low, but I'm leaning towards the bad capacitors on the motherboard. When you fix your board (and check the Bestec), measure the 12v rail with a Multimeter while system is idle. If it's dipping below 11.4v, you'll need a better power supply with a stronger 12v rail.

They probably removed the fan controller to save a few cents. I'm not surprised at all.

Depends mostly on the processor, video card, and the system type (whether it's the older 5v-based, which pulls more power from the 5v rail, or the newer 12v-based). Either way, a 450W PSU might even be good for a mid-end gaming PC with a single video card (as long as it's 450 "real" watts).
