Indeed, i was going to mod my 1200 but it's really not a big case, the layout is a little awkward but with a lovely promotion i'm dying to get a quieter case.
I was looking at the lian li cases but more at the 2120's or the x2000 versions. The only let down is that the 2120's are really bad for cable management if i was to put a window in, and when you have a raid of 6HDD's that you adore and dont want to let go at all! you can't take advantage of the front bays. So the next best think, 2 holes on the bottom of the case and put a 240 rad there, maybe even double stack them, but then that'll kill the silence
