:) Well no more noise than any other tower PC I've had. It serves up itunes to all my Macs (and mp3s/etc to my PS3/360)without any fuss or overly spastic noise. I use screen sharing in OSX to connect to it using my Mini or MBP. I could stick ubuntu on it later on, but there's nothing pressing me to do so just yet (I will eventually, I suspect.) It still sits in the cubbyhole of my super-cheap computer desk in my office, and I use the front USB port if I ever need to reboot it or anything (it's got an insane uptime.) heh. I still have Leopard on it, but that's just because it was the last OS I used before I re-purposed it.

I rip my movies to that HDD and watch them via the uPnP stuff on my game consoles (when the mood strikes me.) It's great for storing music collections, backups and other fun items. I have a dual 2.0GHz (the one with PCI-X instead of PCI-e) that I threw two giant HDDs in and turned it into a file server (time machine backup server) as well as a media center for my PS3 and 360. On other older machines though I have installed both pbbuttons and gtkpbbuttons which support a lot of of the media keys on the keyboard pretty well. However, now that Apple has stopped supporting it, I'll have to break down and put 10.5 on it. I still have 10.4 on mine because it was the last OS Apple produced that was streamlined for the PPC. As others have pointed out, either put linux on it, or put an older version of OS X on it. But it's far from being a "space heater" as you say - mine gets used every work day. Since the G5 was designed for performance, it's not exactly a great file server chip though.
MAC TOWER COMPUTER G5 32 BIT
It's not like it's an Athlon or something that is both slow, 32 bit and single core. The submitter didn't mention what speed his was (I'm guessing slower) but depending on that, a G5 could very well be a useful machine.
MAC TOWER COMPUTER G5 64 BIT
That's still a VERY respectable clock speed, it's 64 bit and the dual procs means it's still pretty fast. Say what?! One of my older machines is a G5 dual proc, 2.7 Ghz.
