No comments on the G5, but I can comment on that LCD. I have the Dell 2005FPW; I believe this is the same exact glass that Apple uses for their 20" at about half the price. I paid $430 for mine after rebate-watching the forums on AnandTech for a week.

I've been working last saturday with a 20" G5 iMac of a friend. Performance and display are very well but to my personal sense the fan is a little bit to load, especially since this machine stands right in front of you. I also had a G4 iMac two years ago but I sold it for the same reason and switched to a Power Book / Cinema 20" combination which work great for my concerns.

In my opinion Pete, you'd be better off getting a G5 PowerMac; why? Because I know what you are like, and in a years time you'll be saying the iMac is great, but you want more. So why not jump a step and go for the PowerMac?

On the positive side; both the PowerMac and iMac are easily upgradable/fixable by the customer.

Good points, Ed, but.. the iMac comes with a 20" screen (compared to £549 for a separate Apple 20") and, well, the Mac Mini is fine right now, but a little extra juice would be nice. A 2GHz G5 with a proper hard drive (instead of the uber-slow Mac Mini drive) should provide that boost.

The PowerMac G5 is good in many ways, but it's too big. I like small when it comes to appliances. I also like quiet, but that might be something I have to trade off. I still imagine the iMac G5 is quieter than the PowerMac though.
