I looked up this board because I was curious- it's X58 with a pair of NF200's, in order to support four 16x PCIe slots, along with 3 more 8x slots. That's cool, if you need that many slots for something, and it is the nicest chipset you can get. And, from one Newegg reviewer's post saying that it fit into a normal case, and a whole slew of reviews that mention no issues with case installation, I'd say you're fine sticking it into a normal case that will fit it's dimensions. Might want to go to a store with a ruler, but apparently the mounting holes are identical to ATX.
Now, tell me, why do you need this board? It's rediculously expensive even for a gaming board. Unless you need triple-SLi and a card for PhysX, you're not going to make good use of those slots, for gaming. But that's not the bad part. A large number of customers have had DOA's or only partially functioning boards, and many of those have had multiple boards with issues. Are you really sure that you need something with this much capability?
