Thanks; I have CS5 on my Mini hooked up to the Thunderbolt Display as well as CS4 on my G5.I got my cube with all the original stuff + upgraded hard drive, apple cinema display, speakers, keyboard, and mouse for $150. I recently saw one on SF bay area craigslist for $50.
Addressing your question as to whether or not you would be able to get some years out of this:
I got my 12" powerbook 1.33 when I was 7. That was in 2002. I'm about to enter my senior year of high school and I still use it. It really depends on what you intend to do. Put on Leopard, since there is much more support. If you intend to use iTunes, browse the web, email, microsoft office, and do the occasional photoshop work then the G5 is a fine machine. However, you're stuck with CS4 I believe...
Even still, CS4 is a great set of programs.
Long live the PPC
