mine's in an xbox 1 case.. two 80mm fans on one side pulling air through the case (yate loon @7v) and a couple of 120x120x15mm fans mounted over the motherboard. other than that, a few added heatsinks, some arctic silver 5, it's standard. This is sat on top of my.. quite modified Xbox1- custom addon IC *ahem* + display, 500gb hd, 128mb ram (extra 64mb soldered to board), linux, xbmc, vga port mod, advance a/v with coaxial digital out, custom painted case, translucent (frosted) backlit jewel, internal lighting, and a PWR-OFF switch on one of my (backlit crystal) s-pads. New bi-colour LEDs, LAN-ACT and HD-ACT LED's (pre-display), aluminium vandal-proof buttons on front panel, M$ remote, usb keyboard(laptop size) and an old chic optical mouse. cost me about £25 to do - got lucky on a dead xbox with the xec+display, used its ram chips, on a £5 xbox. salvaged hd when i recently upgraded to 1.5&2tb hds in my main pc. Dead xbox1 case became live 360 case and i've got a spare xbox1 psu & dvd

Thought about watercooling the 360, i even considered putting it on the same loop as my main pc which is watercooled already.. maybe even add the 360 inside my pc's coolermaster 201 case.. with the pc still in there... but i don't want to chop my cm201 up just to fit a 360 into it - i'd do it to any other case - and the old xbox case is much better set up for cooling than the old 360 case.. not had the 360 long so i'm holding back a bit on further mods
