I'm going to go out on a limb here. What I have is a PowerMac G5, purchased in mid-2005. It's PowerPC, has 2GB of RAM, a 375GB HD, and a dual 2.3GHz processor. Has airport, bluetooth, the whole bit. Someone gave it to me, but I don't need it and personally can't spare the space. I just did a clean installation of Leopard on it, so it's free of any clutter that was on it from the original owner. Cosmetically, it's alright, aside from a few light scratches and two decals I've never gotten around to removing from the side. This computer would be great for running any heavy recording applications like Logic Pro and whatnot on it.
What I'm looking for is a Waldorf Q rackmount, although I'll take just about anything in that general price range that is good for warm pads, is polyphonic, and has a programmable arpeggiator (basically something to compliment my new Moog Voyager). I'm in Texas and willing to ship anywhere (although I'll probably pay out the nose for shipping). In the event of a major price difference, I can throw in my Roland SH-201, which usually resells for around $430. I've only had it for a year and it's in fabulous condition.
