Look, I'm as big a fan of awesome Xbox 360 case mods as the next guy, but I'm not sure I'd drop hundreds of dollars on one. I mean, sure, this transparent Xbox 360 case with a laser-etched Master Chief and blue LEDs is pretty slick, but you're just setting yourself up for heartbreak.
After all, with a normal Xbox 360, if it dies with the dreaded Red Ring of Death you can just send it in to Microsoft and get it fixed under the three-year standard warranty. With this guy, if it breaks you're pretty much screwed. So why risk it? I'd say it makes more sense to focus on the aesthetics of objects that don't have a high probability of needing replacement in the near future.
