The Asus ROG Crosshair VIII Hero is a fantastic board too. The rear IO sealed it for me:
- No Wifi (not needed on a server)
- No PS2 (again, not needed for me)
- No display outputs (I doubt it'll be used with a G series CPU, so not needed. A graphics card will have its own outputs anyway)
- 2.5Gig LAN port (5Giig would be nice, but 2.5Gig is still pretty nice)
- 12 USB ports !
