So I've recently become interested in the PowerPC's, and the G5 in particular because of the way it looks like a mac pro, so cool! I see that these can be had for under $200, but they do have their fair share of problems, including the PSU and water-cooling leaks, not to mention the blown motherboards. I see one listed locally on craigslist for $150 that is 5 years old and has a blown logic board, I read online that the capacitors blow on these things and that the capacitors can be replaced instead of buying a new logic board for $$$$$! I really would like to play around with another back, even though I have a 2011 2.2 i7 at my disposal. Is there a buyers guide or anything I should look at when buying a G5? I looked into buying an early Mac Pro, but I have less than $200 to spend. What model should I look at? I want something air-cooled I believe, but I also want it to be quick, 2.3 Dual Core? I'll be doing some web browsing and light editing on the system if I buy one. What is the latest operating system that will work with a G5? Can you hack snow leopard onto it?
