I had a problems with the card reader and later the hard drive but the service could not have been better.
They can not be held responsible for other's quality control.
Since I now use Linux and many systems with Windows make it difficult to install another system due to them been locked into Windows was the only reason I looked at CCL Computers was the fact that they provided systems without an operating system.
I was going to rate them four stars due to the fact that they don't support Linux, but there service from my experiance is as good or better than others.
Up to know I have no complaints,
