I have been following this case and it is normally $250 for the black and $230 for the White version. Amazon carries this for 240 for black and 230 for white. I haven't seen it for much less from a reputable dealer. After rebate i don't think this deal can be beat if you're looking for an extra large case with tons of watercooling support.
