GR-Tek built a high-end gaming PC to my specifications. The computer was built, tested and delivered interstate in five days. Everything worked perfectly the first time and was exactly what I asked for. Their packaging was supurb, and it protected the computer wonderfully. Oh, and all that extra packaging and the interstate delivery was FREE. Email communication before and after the sale was prompt and answered all my questions. I will definitely be buying my next computer from GR-Tek.
