Just to let all of you folks out there making custom cases around SFF motherboards that they might all look the same but they are not, some are slightly bigger than other. For example the mobo in an Asus XC cube is 10mm wider and 20mm longer than the mobo in a Soltek EQ2000. Now if that was the only difference it would be kind of easy to compensate for but the problem is that the PCI/AGP slots are moved 10mm as well.
I just wanted to let you know since I just learnt this the hard way when trying to replace the mobo in the Y2k-bug which now is officially dead.
