I am running standard bus speed, so no overclocking. The only major change is the addition of a Samsung DVD, CDRW combo drive. Here is the rest of the soecs:
Athlon 2200+
Epox 8K5A motherboard
Geforce 4 4200 64mb
Two 80gb Western Digitals
Two 256mb Mushkin 2700
SB Live Platnum sound
I have 2 fans in the back, 1 in front blowing over the hard drives, and one one the side.
350watt Antec power supply
CPU has a heatsink with a 60mm fan on it.
