Rackmount Server with graphics card or PCI-e?

I couldn't find one... nothing with decent integrated graphics or a PCIe slot.

What about this alternative? Since it seems you've got an unlimited budget, just build a dual GTX 295 desktop. That's enough power for 12 displays, so long as they're all not 30". If you can keep things cool, and have enough DVI splitters on hand, you'll have no problems, I bet.

There are low profile 9(4/5/6/8)00gt cards out there so it seems possible. I doubt any prebuilt systems would have them but you could add one to a 2U system. I would be a little concerned about cooling in such a tight space though, don't know how hot these cards get

not saying its the most practical/cheapest way to go but its definitely possible

edit:
http://www.dell.com/us/en/business [...] =bsd&cs=04 here's a prebuilt with an x16 pcie slot (according to specs at least), not recommending this server, just showing that they are out there, check the specs before you buy

I don't think its the best option depending what they need the graphics for. Those low profile cards seem like they'd burn up easily with their tiny fans. But if they're set on a 2U its at least worth a shot.
