I'm very impressed. Everything is purring nicely. I got the 2.66Ghz with a refurb ACD 23". I purchased 4 more Gig of RAM from Mac Ram Direct via ebay.ca. No problems. They were fast and efficient. The RAM arrived the same day as the computer. This thing really blazes. Especially compared to my G3 350Mhz. I really reccomend a refurb. It's just as good as new and I saved a lot of money. It's a really great experience. I've named the computer Asgard. Thanks for all the suggestions on this forum!
