Summary: As always Lian Li has produced a very high quality case. I see the PC-A12 as more of a budget case where it does not have as many thumbs screws - as the PC-A16 for example -, it doesn't have as many fans, and the motherboard tray is not removable. However the layout of the case is very well done.
Pros: Quality, Strong, Looks, HDD rack can be turned 90°, 3.5" drive bays, Lockable
Cons: Takes finger prints which are hard to get rid of, Finish can scratch fairly easily, Motherboard tray not removable, Only marginally cheaper to other, more featured Lian Li cases
