I have it and think it's an excellent board. Run this badboy with a GeForce 4 Ti4400, 512 MB RAM, and an AXP 1800. The Alpha PAL 8450 fits too. Setup was a breeze, first time I ever plugged in all components and installed the OS on the first try, I attribute that to the nForce chipset.
The only possible problem I have are somewhat random reboots and BSODs. I could go days without any problems and then some days reboot twice during a heavy gaming session. I think it's due to my CPU running around 57 degrees C but have been too lazy to try and bring the temps down, reseating the PAL is a biotch. I also have the FSB and GeForce slightly OCed and the memory timings at 2,2,2 Turbo, may be the cheap OCZ ram I got. 😱
I definitely recommend this board. Have you considered the Abit NV7 133R? Seems to have the same as the Asus and more, with the USB 2.0 and RAID.
