The true is fairly broad, and fairly tall. Dimensions are 132 wide, 64 deep, 162mm tall measured on the one sat on my desk.
I'd have thought most will fit it, have a look at the case dimensions. It'll have to be more than 162 wide, probably by about 4cm. Its an estimate, but any case wider than 20cm should be fine. It fits comfortably in my 180mm wide matx case, which is a 20 quid gigabyte effort and tiny
matc or atx? If atx, he wants the lian li 105n. If matx, there's some more competition.If mini itx, none of the cases will hold it.
