Another vote for the lanboy. Contrary to a previous post, it feels very well designed and not cheap at all. I will go into my experience with it but I should mention I have ZERO experience with a Lian-Li, they were/are too expensive for me.
The lanboy has great cooling and even with the open grill in front, is pretty quiet (a little louder than the Sonota, but not by much). That same grill allows a TON of air flow into the case, so mine stays extremely cool (46 c under load with an anemic CPU fan and A XP 2500 @ 3200+)
I love the hard drive rubber pads as well as orientation, allows you to hide the cables and keeps the drives super quiet. The style turns heads, though from what I can tell is not as professional looking as a lian-li.
I have been running this case for a month now and it has easily been the best I have ever used/had experience with. I love the style, function, saftey (all rounded edges, no cut hands in this case) and the price. I have no doubt the Lian-Li's are awesome cases, but for the money I love my lanboy.
