Just bought a gfx card (Asus EN 6200 TC 512) to go inside my shuttle SD31P. But the problem is it doesn't fit at all. The gfx card is PCI-express the shuttle is PCI-express but somehow the card seems too long and it doesn't fit into the pci-e slot. if i take out the mobo from the case it will fit. Could it be design error of the gfx card? Is this common problem? very strange, never had this kind of problem.
