Go to youttube and view Gaming Rig X58 i7 920 GTX 285. Same MB as mentioned above. EVGA X58 4-way SLI requires 10 expansion slots. The MB mentioned above only requires 7. Antec 1200 has no problem with stand offs, thank you.
So the screw/standoff holes on the classified are the same as an atx board, there's no extra ones? That's good to know cause that'll open up some more choices for a case.
The 1200 does look pretty nice.
