Don't buy that Aspire Q-Pack, it'll only cause problems, and its just not very convenient when everyone else uses Towers. The P180, on the other hand, is an excellent case. Here's a Black
version, just in case.
Here's some other cases I would recommend, keeping inside your budget;
Cooler Master Centurion.
Very popular, and an excellent case.
My personal favorite.
I looked through the rest of your list too, and all I can say is that it looks perfect.
