I also had a major component changed (motherboard) without reference to me first. The board has since proved to be faulty so i'm not best pleased about the outcome. They also sent the pc without the OS key (partly my fault for not noticing at the time)and ended up having to buy another licence off them when i had to reinstall windows. That said their customer service is better than most, e-mails are answered fairly quickly and phones picked up after a few rings. Personally i would probably use them again (with an eye to the issues mentioned above).
