Hi,That motherboard is EEB form factor. The case you choosed is the CM Trooper right? According to their website it supports only micro-ATX, ATX and XL-ATX, I'm not sure if it is compatible, is it? Also have you checked if you have enough space for the coolers and if it is "tall" enough to fit above the ram?Cheers,
SSI CEB is compatible with E-ATX . They pretty much match size wise and only differ in hole position. Up to 3 will not match up, you can drill your own holes, or just ignore it :- ) Since XL-ATX is simply longer ATX, the board would not fit.
