installation is easy. Just take everything out of ur old case and put them in the new one. It's so simple it's hard to explain. It's easiest to do so that u turn the case to it's side and then just put the mobo in (ram and cpu can be in the mobo) it's place and attach it with the screws. Then just put the rest of the stuff in the case and attach them to the mobo.
And the only reason it could fry is if the static electricity does something to it. So ground yourself (touching the case should do) before touching the mobo.
And basicly any atx mobo should fit in any atx case. There might be an easier way but just google for ur mobo type (as detailed as possible) and see if u find something about atx, mini-atx etc. And if u don't know what mobo u have use everest (www.lavalys.com
