Nooby Mistake 1: Not going with a full tower case. With the PSU cables and the wires all over it made cable management a b!tch and a half. There was no real air flow at all with all the cluttered mess inside. CPU ran hot as hell all the time no matter what
Nooby Mistake 2: Not checking to see if my PSU had a PCI-Express cable before buying it. Wasn't a big deal but using the molex cables to power my 7800GT with the molex to PCI-E adapter in place made it a little cluttered in the small space i had. It also made me use 2 molex cables instead of one PCI-E cable, which took away my ability to power more devices.
Nooby Mistake 3: Not buying a third party CPU cooler. Man, the Intel heatsink sucked major @ss. The thing sounded like a jet engine when i played games and when it was idle. You'd think with all that spinning it kept the CPU cool. NOT. The CPU ran at like 50c idle and leaped to 66c and beyond when under load with games. The loud cpu made it so unbarrable at times and it was very very distracting. When i changed the fan speed to silent, the temps sky rocketed beyond 75 degrees. Should have listened to my gut and went with a Zalman, but with the small space inside i doubt a zalman would even have fit.
Other than those three mistakes, which i corrected in my newer build last year, check my sig for specs, that PC ran smooth. When i built my new gamer i retired it and turned it into my new work PC (no more Dells for this household). It was a great experience building it though.
