Ok if I sell my windows PC that I have right now I think That I will make $500 off of it to put towards a macintosh. Should I get a new mac mini or an older powermac? I want to be able to play world of warcraft, listen to music, and browse the web at the same time with almost no slowdown (because thats what my windows pc can do right now without a problem at all). I also want this new mac to last me awhile. Another question I have is how much money would I be able to get out of a Powermac Blue and White 300mhz cpu, 512mb of ram, 30gb hard drive, dvd-rom drive, with osx 10.3 I bought the B&W to play around with before I decided to make the switch.
