I am in the market for a new(er) computer, and the new mac mini has hit the sweet spot for my budget. I really like the features and general power/speed of the new mini. A friend suggested an older but seemingly still fast and powerful PowerMac G5 which are going for roughly the same price as a mini, on ebay. Currently I have a Quicksilver G4 with 933mhz, 1.5GB RAM and it runs leopard decently, but i'd like to have a bit more fun. Would I be foolish to get the G5? Any advice, logic would be greatly appreciated.
