Best G5 PowerMac to get?

Started looking around for a G5 PM. Any one I should avoid? Which one to look for?

The only ones with issues that we have seen are single 1.8s had a legacy issue.

Some dual get their fins plugged up and the fans spin up more often.

Other than that they are solid work horses.

Don' t forget to stay away from the liquid cooled ones. These hosted a number of issues, mostly with the colling system leaking and shorting out the power supply,motherboard etc... I believe they were the 2.5 and 2.7 ghz models.

There are plenty of cases at Accelerate Your Macintosh! News Page - 3/27/09

I've come across a few with leaky pumps, though I wouldn't call it an endemic problem. A leak is pretty easy to check for at least: pull off the side panel and air deflector and inspect the area just underneath the massive "G5" processor cover: if you see a green or rust shaped residue, there's a problem.

Otherwise, G5s employing the liquid-cooling system are robust machines, and I wouldn't avoid them on principle.

I saw one or two leaky liquid-cooled PM's but I agree with Polygon -- ime, a rare problem, not a common problem. Of course, as they age this could get worse, and we're talking several years now since the last one was made, so I guess I would personally avoid them as well. Just MHO.

There are countless articles on these machines, for example: G5 Liquid Cooled - X-Plane.Org Forum

As with any used computer, a peek at the capacitors might be in order, I personally do not know about G5 PowerMacs (so I admit ignorance), but the time frame is "right" (and the problem is well documented in iMacs from this time period).

+ too ........... it won't cost much to look.

I just picked up a G5 1.8 DP PowerMac from Macdoc and couldn't be happier!

Thank you MacDoc !
