The website is excellent, allowing you to quickly explore many detailed options with good capsule descriptions of technical issues. Once the decisions are made the assembled computer is promptly delivered. Having a silent computer has greatly enhanced my working (and playing) environment. One small warning - if you want a fanless system look carefully at the specs for the case - one of the fanless cases actually had fans in the base of the case. I don't know if this is a significant issue, but a truly fanless case works just fine.
