the corsair 650D is built like a tank and looks like a small full tower case. the cable management ability on their cases (in their price points) are second to none but unless you re-build your PC consonantly, that feature is often over blown. the corsair fans are decent but not great ( i replaced all my corsair case fans). they tend to be loud and from previous reviews I have read, the 200m don't move that much compared to other fans in the market and can make a rattle noise (from 600T reviews)
the lian li has solid build quality, solid cable management and solid fans (although I doubt the rear is silent @ 1500rpm). it basically does everything good enough and at that price, its a hard case to beat. i would take it any day over the CM690 II linked by saint19.
if you need the space, the corsair would be the way to go but if you just need a good case it's hard to argue over the lian-li. as is cases are mostly about looks, get the one you think looks best in your home.
