After a long debate on weather or not I should get it, I got myself a Power Mac G5 Quad Core. So far it has been a great machine and served me well, even thought I've only used it for a day now. My biggest issue when considering getting one was the liquid cooling system, I need to find info on how to maintain it and keep in check, any information would be appreciated. Most things I can find are for the Dual 2.5 and 2.7 cooling systems, not the quads thought I assume they may still be correct for the quad I don't want to take chances. I have all my daily tasks covered, but would like some games for my freetime, but outside of emulation idk what to install, how about some ideas? Is it worthwhile to upgrade it? If so, where are my limits with video cards? Can I multi-boot? I want to run linux on this machine as well, but I don't know how well its supported on Liquid Cooling G5s, yet alone G5s in general. I would also like to play around with other OSes like Morph OS, which I have never messed with at all and I'm not positive support multi-booting. Thats all I can think of for now, thanks for the help in advance .
