The PC-K62 is a great case sure its a plastic front panel but you know that when you buy it; its supposed to be a cheaper version of a great lian li design. The Inside layout of the K62 is brilliant, lots of places to store the cables, plenty of room and has tool less features that WORK eg. the hdd bays and the pci locking mechanisms, not bad looking either.
These new cases look or seem to have the same general layout inside but a messed up front and top panel, the K57 wouldn't be so bad if they just made that Decepticon bit bellow the drive bays just plain perforated mesh the other cases have no hope!
There only was 2 series of case, the metal boned K7 blah blah and the ones based on the K62.
