Ahh the Performance series, they remembered us again!
The P180/182/183 were top cases, I still have my P182SE, may rebuild into it. The P280 could be so much more, but it borrows little from its predecessors except perhaps a door (which is much less sleek, don't like the top), and the internals are decidedly run of the mill. Nothing interesting there at all, plus the tool-less bits look nasty cheap. I've had 3 Antec cases (still have 2), but I'm not impressed with the P280 yet. The Solo looks nice, if the price is right.
