So, I was looking through American TV's ad this morning for their warehouse sale and noticed they had Mac minis (PowerPC) starting at $299. I called up and while my store did not have any, they had two in the St. Louis area — one 1.42 GHz/256 megs of ram and one 1.25 Ghz/256 megs of ram for $349 and $299 respectively. Both are the combo drive models, but that's not so bad.
I bought both of them. They're going for more than that on eBay, after all and they have a 15 day return policy if I get buyers remorse.
I thought I'd mention this truly great deal in case anyone has an American store in their area. Seems like a great deal. I have a sample copy of OS X Server that I'm going to put on one of them. Maybe the other will be an extra computer workstation or something, I'm not sure.
