So I'm trying to sell my Mac Pro 1,1 (bought in 2007) and in a check-in suitcase the metal 'legs' for lack of a better word, bent a bit. I've been able to bend it back reasonably, but 3 of the 4 corners where the side panel fits in have a bit of a gap away from the main chassis of the machine. We tried some clamps (they pop back out) even with superglue so my last resort (aside from just eating the extra loss and selling 'as is' - cosmetically deficient but functioning well) is to consider welding to close the gap. My buddy thinks the main chassis is steel and the 'feet' (on top and bottom) are aluminum. I think it's probably all aluminum - which can be welding to aluminum, but wanted to check with you guys. http://www.apple.com/macpro/specs.html says 'highly recyclable aluminum enclosure' - do we think the original Mac Pro is the same? It's heavy!
