Meh, looks like a carputer!
I might cut down the ram if I were you for faster boots. I find that the longer I have to stare at those start up screens, the more I get *****ed of at it.
Faster boot = happier with 'puter! (at least for me)
I also went with a 7400 rpm drive (3.5 though) in an attempt to speed up accesss. Although I probably roached that idea with a 320g drive (I have A LOT of music and videos on there)
