I purchased this PC for my parents who just need a basic PC, but needed the ability to add a previously purchased hard drive and graphics cards. I could not find a branded pre-built system that had the specification that I wanted, but PC Specialist's PC configurator give me all the options I could want and more. The PC configurator is very good and does highlight incompatibilities between components, but I can see how this would be daunting for someone that has no knowledge of computer components, but if you know what you are looking for they offer excellent choice. This is the second machine I have bought from PC Specialist and I doubt it will be the last, I have also recommended them to friends in the past.
