looking for the smallest case for my build

[bimmerboii]

i've been moving houses for quite sometime now (im living in university halls) and i move 2x a year! and also when i go back home for the holidays i bring my computer with me. now im really getting tired of the bulkiness of my pc. can someone please recommend me a small or compact case that would fit my system? im not familiar with the terms shuttle or atx or microATX or stuff like that

these should all fit in:
mobo: p35c-ds3r
3870x2, ocx reaperX (mind the extended heatsink)
x-fi extreme gamer, thermaltake 750w

If you want to keep the motherboard, you won't be downscaling much. Case Central section thread
