I had some problems with certain files and the RAID crashed one time so I rebuilt it but with a lot of installs gone. So I'm still testing it. I've already managed to take up 600GB from the Terrabyte RAID :)
Yes, I bought it just in time! I got Call of Duty 4, Gears of War, Bioshock, Timeshift, Dirt Racing, soon some other new generation games and my 'old' games, too. Never had so many big games installed ^_^
So, if nothing happens from now on it will be a great machine for the coming two years.
