I had a Lian Li 7B plus II case for about 3 years. Last month I replaced it with a Corsair case. They both have and aluminum front panel and a clean, professional look.
The corsair however has: excellent cable management, painted interior, filters, tool-less drives and side panels, heatsink cut-out, noise dampening, better front I/O placement, and is not a finger print magnet like the Lian Li.
Well worth the extra $30. Sure it weighs more, but its not like I'm carting it off to LAN parties or something.
Lian Li just feels overpriced when all you get is a lighter chassis and a clean look.
