I guess after reading the comments I won't be picking up the set after all. My reservations mainly stem from comments against the longevity of the G5, even as a box to tinker with. The price advertised didn't help either.
In general, I believe that most of the reliability complaints of the G5 stem from the later generation ones which had a liquid cooling system (that eventually leaked).
For example, my "daily driver" home machine is a 2003 PPC G5 PowerMac (single CPU 1.8GHz)...all air-based, so I'll never have to worry about a water leak frying it. The only hardware that I've had to replace has been the DVD burner.
I have found that it does hang occasionally on a script that I've set up to run automatically (automatically downloads my website's log files), but I believe that this probably stems from the fact that I've never done a true "Clean" install of the OS since 2003...and its now running Leopard (10.5) and had Tiger, Panther and Jaguar all previously installed. I've been meaning to get around to backing up all of my settings in keychain & cookies & [etc] so as to facilitate a true clean install to see if I can eliminate this inconvenience...FWIW, this little bug didn't show up until Leopard.
Today I found this>
Dual 2 Ghz PowerMac G5
4.5GB DDR SDRAM
GeForce FX 6600 128MB
500GB Hard disk
DVD RW Drive
Apple 22" LCD display
Apple keyboard
all for USD$520.
Seems like the powermac g5's are really coming for me!
IMO, not bad, considering that it includes the 22" LCD display and a good amount of RAM. However, what's missing is how much the seller is going to charge for shipping - - that's a hidden ... and not trivial .. expense.
In any event, the real strength IMO of the Mac Tower is for internal HDDs for convenient storage ... with a Sonnet Jive and a second SATA card, one can install up to five (5) 3.5" HDDs in a G5...although from a thermal management standpoint, I'd recommend running "only" four (the A/C in my office gets overwhelmed in the summer, which makes the G5's fans spool up).
My current hardware plan is to hope that Apple's next bump of the Mac Pro is a good one, and then probably repurpose my G5 around as a file server for keeping data backups on, and the like...with the likelihood that I'll probably reinstall Tiger (10.4) on it to have the OS 9 "Classic" mode around in case I find some stuff in my archives that still needs ancient software capabilities.
An alternative would be a Mac mini, but from a data storage perspective, it is pretty easy to nickle-and-dime one's self with external HDDs .. particularly if one goes with the better I/O of Firewire instead of USB. A lot of the question still comes down to what one expects to be using the machine for...if it is anything that's likely to be CPU-intensive, most people are probably better off with a more modern Intel machine.
