AMD Ryzen 4000 desktops are coming soon, using the mobile APUs rather than the desktop line of 4000 processors. They are a little bit over budget at $300+ but they are going to perform excellently ranging from 4 cores / 4 threads up to 8 cores / 16 threads and very decent iGPU. If necessary this could be repurposed to suit a number of uses like a modest workstation or 1080p gaming or some virtual machines or a media PC etc. https://www.cnx-software.com/2020/06/16/asus-pn50-the-worlds-first-amd-ryzen-4000u-mini-pc/ https://www.cnx-software.com/2020/06/16/asus-pn50-the-worlds... There are a lot of older, competent dual core machines available on Amazon very cheaply too. These are much cheaper but if you ever needed even one virtual machine it would be quite taxing. These machines are 4 or 5 years old so linux support is likely excellent. https://www.amazon.com/s?k=small+form+factor+pc&ref=nb_sb_noss_2 https://www.amazon.com/s?k=small+form+factor+pc&ref=nb_sb_no... These aren't strictly "SBC" but they're very similar. Basically laptop motherboards and soldered chips with potentially upgradeable storage/ram.
