Thanks, that is really expensive for a sheet... I'm looking for some type of metal that is ~3mm thick that is cheap.
Now, if I were you, I would not blow that much money on a setup. Go for some old ATI cards that are rated really well for M/hashes and throw a bunch of them on a decent motherboard, but not an expensive motherboard like the EVGA one.
Thing is now days the cards the old cards cost as much as the new ones.
