I'm liking the comptuer, yet I'm not being funny, but I wouldn't trust the amount of hard drives:
Hd- 5 hitachi deskstar hd's at 500GB EACH! THAT'S TWO TB's!
I wouldn't be able to fill them up even if i wanted to, and if any failed...er...no, so I'd lower this down if i ever bought this pc. I'd just want one until i filled it up.
Until a storage device comes into play that can hold that much, and fast enough to not take ages, i wouldn't want to use 2 terrabytes, because if they went..wel...bye bye...
