<human>: Can you provide a brief overview of the text?

I ordered a computer on 10/01/2011. I built a modest system that ran me right at $900 after shipping. I ordered it with the CoolerMaster HAF 92 case. Approximately 2 weeks after ordering it, they send me a message saying there is a delay due to the case being backordered. I figured okay, that's the case I really want, so I'll wait it out. I wait an additional week and finally it's built and sent. 

I open it up today and it's completely the wrong case. Instead of my nice CoolerMaster HAF case I have a shitty plastic Apevia case with a giant window and the power supply on top, with half the fans that the HAF had. I immediately call customer support for CyberPower and was on hold for almost an hour before I had to give up and go to work.

What should I do? E-mail them? Sit on the phone for 2 hours hoping someone answers? The online chat was just as worthless, just kept saying all operators are busy. I don't want to send the computer back because I would be computerless for another long period of time with their slow asses.
<bot>: Cyberpower sent me the wrong case for my computer then didn't answer their phones for an hour when I called. What do I do now considering I don't want to send it back and be without a PC for another month.
