I bought this a couple years ago but I am now using a PC again as my main machine (after learning how to build them myself). It comes in great condition running OS X Leopard and has original keyboard, remote & backup discs. While I still have the mighty mouse the scroll wheel is a little messed up on it so i will chuck in a Microsoft intellimouse for free with it.
It originally came with 1GB of RAM but I added another 2GB just after I bought it.
If you have any questions feel free to ask.
EDIT: I may be interested in part exchange if you happen to have a very high end graphics card or SSD lying around.
WIll require either cash on pickup or for you to pay for a courier and pay before it is picked up. I have the original box so it can be shipped in this if necessary.
