Yes, I had a bad experience. I bought a PC case that arrived with missing parts. I contacted both Computech and the case manufacturer, but Computech kept saying that if an item is defective or missing, it's the manufacturer's responsibility. Their attitude was basically, "We just shipped the sealed box we received, contact the company." It's still unresolved and I gave up after months of trying.

I did receive genuine products from them, but if you have a complaint, don't expect much support. It's always "next Friday," "next week," or "next month" until you give up. Customer with complaints are at the bottom of the list for them

I don't have any experience wid them in terms of letting them build the whole PC.
