Make the front of the modded case the side part so the case sits sideways (the side of a normal comp will be the front). You could have a bunch of fans and it would trip people out.
ooo...modding a case...whats your favourite game? if you have one...ive seen someone mod a case to a Half Life2 theme...really cool...ill post again if i find the website
It would work, basically just turning your case 90 degrees counterclockwise, the mobo wouldn't be moved at all. You would just have to cut out the back panel, move it to the side and turn the drive bays clock wise 90 degrees.
I have a friend who took the side panel on his case to a local shop and they profesionally cut out a design that he made on auto cad. Looks pretty cool.
