What case should I get?

[Salaskan]

I'm not sure which case to get. I have to move my PC twice a week, so I need one that is durable and preferably not too large/heavy. It's also important that the case is silent, expandable, and that it has at least 5 USB slots. Also, it has to be compatible with a P5Q Pro motherboard, but I don't suppose that's a problem. What case would you suggest?

Another question: Is a 520W CoolerMaster PSU and a case with 1x120mm fan sufficient when I have an overclocked E8400, a HD4870 and 4GB RAM?

I've composed the following system:

Any general comments/suggestions?

Thanks in advance!

Antec is not to bad. Ultra has some nice cases too. You should look around and maybe you will find something that suits you.
