I have seen several posts on the web on installing PCIe x8 graphic card on server motherboad.
I have a IBM X3200 M3 (Xeon 3430 Quad Core) server. Though the server has onboard graphics, I could install successfully a PCIe x8 graphic card.
ASUS GT-730-SL-2GD3-BRK
It takes some time (30-60 seconds) for IBM IMM to show up but works like a charm.
Trust this helps those who would like to convert their server into a kind of workstation.
