I have built a computer with both this and the lian-li case.
Here are my thoughts.
The coolermaster comes with blue led's and a top blowhole. Defintate pluses.
On the other hand it is a fairly small case and felt cramped. Futhermore there was no cooling for the hdd's like the lian-li and the thumbscrews felt cheap on the coolermaster. There is only room for two fans and the included ones have rather anemic airflow.
Overall the lian-li case was easier to work with and had more room and cooling.
The coolermaster however is very nice especially the door. Another plus for the coolermaster is that it has a slightly smoother and lighter finish tought it seems a little more flismy.
Overall if you intend to have scsi drives or a larger system (many drives etc..) i would go for the lian-li. On the other hand if you belive in fashion over function and have the cash then the coolermaster is not a bad choice...
