This sounds similar to a build I'm planning. I cannot find the workstation mainboards at a reasonable price though. They start at like 400€ in Europe.

There's an Asus one that's available as well, the ASUS C246 PRO - it's about 250 GBP.

I did build mine 2 years ago, so the 246 motherboards are less available now, the C252 is another option which will take you up to 11th gen Intel.
