Hi all - I have a powerbook G4 I'm using for school and my main machine, but have a 20" screen, keyboard, mouse and all of that I hook it up to when I'm home. I love Civ IV more than eating, but the powerbook is KILLING me with slowness. I was thinking of getting an older or lower level machine to game with and use for itunes storage and such on the side - either an intel mini or a G5 tower. Which do you think is the most cost effective for me to play WoW, Civ IV and maybe a few other current games? I don't need blazing, but I want to play those significantly faster than the powerbook can (WoW actually runs fine on it right now.) I was going to use ebay or craigslist as well as our forums when I buy - but was interested in opinions on how much to spend, what to outfit it with and which machine would suit me. Like I said, I want something to take my desk space at home, so iMac and such is out. Thanks in advance.
