I needed to build a powerful PC that could handle 4K video editing and lots of gaming. The interface of the PC Specialist website is very straightforward and the options provided for each component are broken down and easy to interpret (assuming a prior knowledge of computer hardware, but even if this is not the case, you can make inquiries directly through the chat to help with your build). The build time, testing and delivery was incredibly quick and I received the PC within a week. It was easy to get started and mostly plug and play. Very satisfied with the service and will definitely make use of the upgrade service in years to come.
