“NewEgg does have some good buys on refurbished units. And hey, thank God we even have such choices”
I bought a HP 600 G1 SFF off lease PC via NewEgg in April (iSell 3rd party, fulfillment by NewEgg). I bought it as a stopgap until I can work on a new higher end build. It was $169 after $20 rebate. It had a 2015 build date so it had came off a three year lease last Fall. Grade A condition, with a 2 year seller warranty, i5 CPU, 8gb RAM, Win 7 pro which I upgraded for free to Win 10 pro. Platinum Rated PSU which can handle a 1050ti GPU if required. I added a DVD burner (it came with DVD read only) and another 8gb RAM for $35. The new build can wait as it more than meets my needs.
Yes, that looks like a good buy also. I looked it up and even now it is 160.00 at Amazon (NewEgg not in stock). The Intel Core i5-4570 itself goes for $190, and its performance is rated close to the Ryzen 3200g, though I do not like SFF (small form factors, and i am surprised you had the slots for 4 sticks of RAM), and it must be fast. Replacing the 5400RPM SATA HDD with a 500 GB SSD for $50 would provide a very noticeable improvement.
