Intel’s not good for power efficiency. Id recommend any old entry level b550 AM4 motherboard, drop a ryzen 5600x in it, buy 32 gigs of dirt cheap DDR4. You’ll be out the door $250 and be in amazing shape using half the power of Intel’s hungry 13th gen 14nm+++++++++. If you wanna spend a little more get a 5800x for 2 more cores. It’ll handle all your server stuff no sweat.
