$150 (roughly the cost of APU2+case+power brick+16GB SSD) for a t620 would be daylight robbery. I got the non-plus variant on the secondary market for $30 delivered and it works very well, uses roughly the same CPU as APU2 as well (4-core AMD Jaguar derivative, AES-NI & AVX extensions). Power usage is 6W idle (headless), 12W full-load. UEFI is basic but functional, I can boot Linux straight from the EFI boot entry. t620 Plus has a PCIe riser so would be better suited for a network gateway. The Wyse equivalents from that era would be Zx0Q/Dx0Q series although I don't think they had a PCIe version. Another interesting option is something like Fujitsu Futro S9010/S940 (4-core Goldmont, you get SHA ISA extensions which is nice), has a PCIe riser as well, but there are fewer of these on the secondary market.
