I refuse to buy another Antec case. Their customer support is great, but the products are still flimsy. I bought a P180 a few years ago and had to replace both doors twice due to warping, and the front door 3 times because the slightest bump on the hinge causes it to shatter. Not to mention it was a pain to build in and there wasn't any space for cable management what-so-ever. Worst... case... ever.
Now I'm rockin' a Lian-Li case. It's still not ideal, but it's leaps and bounds better than the P180.
On another note, people need to stop negatively voting on comments because their opinion is different from your own. There were two legitimate comments on here that were hidden because they just weren't impressed. I, for one, am not impressed either. The PSUs are only bronze rated and stop at 750watts. Not enough for a solid high-end computer these days. The cases are just P180 variants with mild improvements... nothing ground breaking.
A good case needs to be easy to build, spacious enough for long video cards, have a good cable management system, have positive air pressure w/ decent fans and filters, keep noise to a minimum, and MUST BE MADE OF SOLID MATERIALS ESPECIALLY IN FREQUENTLY STRESSED AREAS (no plastic joints, no warping materials, no weak glue, no flimsy buttons or switches, etc).
