Scan are my go to supplier of computer products. The selection is wide, the prices fair and delivery prompt. After sales service is excellent. The High End {Hence Pricey} goods they supply are labelled as such, so you know if and when you are paying a little extra for quality/performance. The website also carries a Custom Build section that non-expert buyers can use as a basis for building their own Custom unit, and be confident that the individual parts will fit together and talk to each other. The website WORKS; it is attractive, easy to navigate and informative, all positives, no negatives.
