I dunno, mine died after a small crumb managed to land in the track for the laser disk reader. My original XBox is still going after three cups of soda, two cups of water, half a pizza's worth of vomit, and a snapped disk tray(we had some wicked parties when I was little, haha)...
EDIT: Oops, hit submit a little too quick. I meant to say that I am following this build intently from now on, because my cousin is a die-hard Metroid fan, and I was thinking of getting him into this armoring business for a suit of his own as well. Haha, I bet he'd love to do a PED trooper, I'm pretty sure they're his favorite units in the whole set of games!
