I put this PC together a few years ago. Back before I really knew much about building them. The computer runs great and has played every game I've thrown at it. I'm currently making it into a MAME machine (complete with cabinet and Arcade controls) and am looking to upgrade the GPU as well.
When I got the PC together for the first time, it wouldn't power on. I thought the button on the case was bad and replaced it. When it still didn't power on, I bought a new power supply (the original one was a $10 nameless one). After I hooked up the new Corsair PSU and it STILL didn't power up, I checked the motherboard. It was shipped with a CMOS jumper. after putting one on, it fired up.
The H100 doesn't really fit the case, but luckily the case has holes in the top, so I was able to get it to fit, but I had to put the Optical drive lower so it wouldn't bump into it.
