So I got giving a barebones HP Desktop Pro A300 G3 with its dmi data missing in bios. Managed to snag a Ryzen 3200g and 16gb tforce vulan ram for 30 quid! Having to use a 60gb SSD (Ubuntu) and a new condition and really low usage 1tb HDD that's only 5400rpm. The power supply is 180w gold plus so I may have to drop the ctdp down of the ryzen to say 35 or 45w just so I have safety heard room.
I already had internal WiFi and the rx550 so got it all set up and going.
People going to ask why I'm using a rx550 with the Ryzen having vega 8, its because I cannot use xmp and HP board has capped the ram at its jdec speeds so the rx550 has been shot in.
Even with a messed up bios it works really well for what I use it for and it really quite. Can play all the games I needed it to and really good at streaming 4k on bedroom TV.
If anyone comes across any am4 office builds, snap them up! This one has really helped me out in a pinch.
