Lets start a bit of a community project here! Like some of you may or may not know, we already started abusing this Antec 902 case over at Assembly 2011, but now the party is over and I'm out of ideas.

The stuff done so far:
Flip the thing 90 degrees, so the rear is no floor and the front is the roof.
Lift the motherboard tray and I/O-area 40 mm so there's room for cables.
Cut a small window to the front/roof and flip the fans so the cooling makes sense.

So not much done... Yet.

To help with the inspiration and ideas, there's a SketchUp-model of the case available at: http://sketchup.google.com/3dwarehouse/details?mid=6fb65033d8293077450b643c5e3aa18a&prevstart=0
