I have also bought some stuff at Power Computing. I bought an Mirage 4000 Pro Tower, and a original A4000 keyboard, at least I thought.
The things came quick, but when I opened the box I found a A2000 keyboard :-( (Hopefully the Mirage tower was the right thing...)
I mailed them once about this mistake...No reply... I wrote them once more...Still no reply...
After writing several email to them about the A4000 keyboard, I finally got an answer. They told me that they would send me the adaptor so I could use the A2000 keyboard in my A4000. Yeah stupid, I want to get what I paid for!!!
It has been the only reply I have gotten from them, eventhough I mailed them several times, because I rather would like to have the A4000 key instead of A2000 key. The don't write me back, so they lost a customer there.
Due to their poor support, or should I say no support at all, I will newer purchase any more things at their shop. I would rather do my trading in Germany.
I hope people would see this as a warning of Power Computing. If you need support for the things you buy, you don't get any!
