Have nice and easy to use online configuration tool, that checks your selections (in case of incompatibility). The ordering process was easy also. After a couple of days of seemingly no progress with my order, the build and testing was rapidly completed. The delivery was the usual non-event, although it was the first time I've needed to give a PIN number (emailed to me by PC Specialist when the PC was dispatched) to the driver (makes sense, given the value of the PC). As soon as I got the PC, checked it out, removed all of the packaging (including foam packing inside the PC), plugged it in, and installed Linux (Mint Cinnamon) - did not order/pay for Windows - which works a treat.
