Take your pick!
My gf's bro owns #1
I own #2 (I like #2 better for personal preference of having the drives hidden)
#3 is the same as #2 but it has some cool looking blue led scratches that make it look pretty sweet.
Now...#2 and #3 are much more feature rich than #1 because of the hard drive dampeners (hard drive silencers). They have a cable organizer at the bottom and 2 removable hard drive cages. They also have rails for the cd rom drives.
