It's been awhile since I've used an Apple, I own numerous PCs. Anyways, I'm headed to a computer auction at Abilene Christian University this weekend. I'm particulary interested in this; "Powerful G5 Powermacs with Dual 2.0GHz Processors, 1.5 GB, 150GB HD, DVD burners, and Apple Studio LCD Display!" I haven't seen a decent price for this online. Any estimate what I should pay (limit) at an auction for it?
