Anyone looking for a barebones system to build a highly integrated Windows 10 PC may find themselves considering the ASRock DeskMini H470W. For just over £200 you get a tiny STX chassis and motherboard along with an external power supply of the type used with a laptop. You need to supply a 10th Gen Intel CPU, DDR4 SODIMMs and an SSD and could have your PC up and running for somewhere around £500.
