The only modification to this board was to remove the noisy chipset fan and replace it with a Thermaltake EasySpirit II heatsink. I didn't like the 40mm fan inside that, so I replaced it with a Scythe Minikaze fan. Also replaced was the 40mm fan behind the MOSFETs, also with a Minikaze. Very quiet.
NOTE - before you fire the board up you will have to correctly install the EasySpirit II heatsink!
This board is a real trouper, and has everything you need for a top-notch socket 939 system:
Supports Athlon x2 to 4800+
Dual-channel PC3200 memory up to 4GB
Hypertransport 2000MHz
PCI Express
nVidia SATA2 four devices (w/ RAID)
SiS180 SATA two devices (w/ RAID)
Dual LAN
Gigabit LAN
192Khz 6-Channel sound

Return for DOA only and that assumes you can properly install a motherboard and a heatsink.
This is a working pull from my own system, and comes in the original box with the manual.
