You probably could, but I'm not sure that would work correctly in a non-server board. I think any server board that has a x16 slot would be fine since more servers aren't really designed for using high-end graphics. > My concern is that these x16 slots on motherboards are being primarily > used for video cards, thus I ultimately have no idea what the > manufacturers are testing them with.

Looking at Supermicro's site, it seems that pretty much all of the 5000V and 5000P based motherboards have at least one x8 slot. The 5000X based boards have an x16 slot, but those are workstation boards which would likely use that slot for a graphics card. Look at Supermicro's site under Xeon 5300/5100/5000 motherboards. You should be able to find a board that would work just fine for you. Jaime Bozza Qlinks Media Group
