The best place bar none to buy your custom built PC.
I finally made the jump and bought a high end gaming rig, and PCS was the only place to go. This is my third PC from them and as usual the service was first class, from the customer service through to the professional build and A1 delivery service. When you're spending over £1800 on a PC you want to feel safe with a company you trust, PCS are that company. You know you're in good hands, especially with their outstanding after sales support.
I can't recommend PCS highly enough. For a full, in-depth review of the service, the shipping, the build quality and the performance of the rig with photos, copy paste the link below into your web browser.
