Why not stick with Antec. The P280 is a nice case. My last build was with a P180. Great case to work with. http://www.youtube.com/watch?v=BXUz2IgFAlI
Antec Support is A-One. One of my side panels was slightly warped, so I called them. Agent did not even ask to return it. He just said that happens sometimes if they sit on a loading dock in hot weather.
All he wanted was my address and a new panel arrived in three days.
