I'd recommend the following to replace your Atom ITX board. If you need more ports you can either go with LSI 9207-8i HBA pcie card for 40-50 bucks or one of the those m2 to SATA adapters.

Intel Core i3-9100F - $72

Supermicro MBD-X11SCL-IF Motherboard - $197

2x Kingston KSM26ED8/16ME 16GB DDR4 2666 ECC UDIMM - $187
