It's not bad - drive is easy to change - RAM can go to 2 gig easily.
I'd say it's "fair to good" BUT make sure it's a Superdrive - that's a none standard config.
There are two distinct markets going on right now -Intel and not Intel and they do not interact much.
We sell G5 models 2:1 over Intels with the exception of the Quad MacPros where they outsell the Quad G5s ( not by much )
I am surprised.
Get this - 76 MacMini g4s in the last month and demand for more.!!!..dman hard to find in quantity too.
Despite the excellent value and performance of the Intel Macs ( which we love ) the market is divided.
