Sorry to bump a very old topic but as I was just dismantling this unit and filling the giant holes in the wall it made me reminisce of good times when I was an avid user of XBMC4Xbox. I'm looking to sell the house so have had to dismantle the old girl, it was a fun (and at times extremely annoying) project and each year the unit got a new look. Sadly I can't find any recent pics of how it ended up but the control panel got a modification and there was a cut-out for a dual xbox360 charger station.
For anyone interested here's a WIP photo which I think was taken about a year after I initially posted this thread 4-5 years ago:
The design didn't really change too much from that, added some blue leds and integrated a sound system into it (think you can just about make out one of the small speakers integrated on the left hand side of the base). Had a go at hooking an xbox up at one point too and splicing up an old controller so I could use the control panel on the Xbox - that worked pretty good but the only thing I missed was the touchscreen pub games so it didn't last too long sadly.
Anyway that's my little trip down memory lane done, not sure if I'll be creating another one at our new place but hopeful I can have a proper office/games room and if I can then there's a good chance I'll be reusing some of these parts and definitely hooking up an Xbox original too
