I've been asked to do another PC for someone at school, but this time, he's got big bucks and wants watercooling and a cube. Basically, which case would you rather have? I'd go for the LL because I think it looks better and can take soooooo many drives, but the UFO can take thermochill rads (I've never used them before ) which are supposed to be better cooling that BIX's ect. Also, the LL is cheaper, so i'm stuck for choice.
The Lian hes the look of a finished item about it for sure where as the UFO has the look of a more custom affair and indeed the ready inbuilt rad features !! From what i understand, you can buy extra kit (upping the price mind !) for the Lian like rad mounts and other options ! At the end of the day its personal preference but i opted for the MM :- http://i83.photobucket.com/albums/j303/richmawr/PICT0018.jpg
Personnel preference wise, I hate the idea of the cube, but the Lian Li 343 seems a lot nicer. Get a G70
I've gone for a Brushed Alu UFO Optimax 1203. Aqua-Pc's now sell then and can get them inunder a week.
