Getting an RMA for the whole system will not be a problem. Leave a message on their phone line, and they will return your call. My CP system arrived several weeks ago and, after booting up once, it died. The system would not post and all three error lights on the motherboard came on. On New Egg, I noticed that a few other users of my motherboard had similar issues...so I guess a got a bad one. Anyway, I called CP and they RMA'd the whole system. I also had them rewire the CPU power cord as the original wiring blocked the PCI slots.
My RMA'd system was returned to me last week and everything checks out OK. I did notice a few scratches on the window of my HAF-X, and so they are going to send me a new side panel.
I like their customer service, which is in CA rather than China. Yesterday, I called tech support of Asus and I got a guy in China who had me reflash my bios for no apparent reason before I was transfered to Asus tech support in the USA. Fortunately, I knew enough about my bios settings to reset everything---the system wouldn't even boot until I reset the Raid settings---but it pissed me off that he had me reflash the bios before determining if that was even necessary for my (minor) problem. Oh, btw, the problem I was having was a voltage error reading with the program, Asus PCProbe, and the USA tech support said it was a software glitch, LOL.
