It's because the CPU power (or whatever that is?) won't reach. I had to help a guy whose came undone and to make matters worse, he had a 2x120mm heatsink covering it up that we tried to avoid taking off. Man that was a pain.
just the style of the case really. i was surprised to have the powersupply on the bottom of the case. Most cases hold them up top. Well i love the case...and as for the motherboard...having it kinda centered makes it easier to hide all the cables and what not. Notice how clean and cable free the case is .
well the antec 1200 is an amazing case all together. one reason why i chose it for my gaming build. Lots of space...and its neat...therefore lots of room for upgrading and adding .
