I have had this computer for just over a week now and I must say I am very impressed. I will start with the order itself; it look 13 working days in total to get from order processing to the point that it arrived in my hands, so the build was completed (as advertised) within 10 working days.
Secondly the delivery: The computer was delivered by a good courier service, still in great condition and the guys at UKGC had put Foam packaging inside the machine to ensure that none of the components would move around in transit.
Performance: Easily one of the best computers I have ever used. It is quiet, it is fast and I have yet to find anything that will not run with it on ease. (For the record I have so far played: Starwars the old republic, Starcraft 2 and shogun total war 2 on full spec, and with ultimate performance the computer just shrugs it off, barely making a sound of effort.)
Overall I would totally recommend this computer and also this company, it is hard to find genuine companies that work hard and strive for great service and great product.
