If you are referring to the 867 Quicksilver Single processor, I own one and I am very satisfied with it. I had a strange problem with the Superdrive about 8 months after I bought it but I was able to convince Apple it was in fact a Hardware failure and they replaced it. Other than that it sits in my "computer room" and hums along in OS 10.2.2 without a glitch except for the occassional self-induced ones. I feel it's a great machine and I sometimes tend to neglect it because I use my Pismo laptop for most of my home projects because I can sit in my easy chair watching TV. But for scanning projects and DVD authoring it works well. Joe Ellis
