You have to install a graphics card - like with any other server/workstation motherboard the onboard graphics are crappy. I would order one from the US if you can't find a UK retailer, these are the most easily obtainable and affordable owner controlled boards.

https://raptorcs.com The TALOS 2 - made by the same folks who did the coreboot ports for the D8 and D16 boards It is pending RYF certification, is 100% owner controlled and it has libre firmware from the factory. POWER is the only owner controlled performance CPU out there, IBM publishes a lot of documentation and there is absolutely no hardware code signing enforcement not even for the microcode. Please note that 5K is an average price for server hardware in that performance class, there are a variety of lower end owner controlled options if that is too much/if you don't need something that fast.

You can install a FM2 CPU on that, the plus has PSP the regular doesn't.

Define affordable? People have gotten used to intel's cheap CPU's that they don't really own - even just 15 years ago computers used to cost significantly more. I remember when the P4 was just released and crappy pre-builds were going for 2K+.
