Yayyyyyyy!!!!!!!! OMG, this is the most beautiful computer I have ever seen. I will give you the quick and dirty so I can go back to playing... It is not that hot, so far it has been completely silent, I have yet to see a single imperfection, the 5400 RPM HD is a Hitachi, it has OS 10.2.7, and damn is this fast. It booted up seriously fast compared to what people complain about and everything has been serious instant loading. Oh, and wow is Safari fast...my God!
