Your best bang for the buck on used PCs are any of the Lenovo / HP / Dell small "business desktops". Typically known by their Tiny / Mini / Micro name (Tiny = Lenovo brand, Mini = HP, Micro = Dell).
For instance, the HP 800G5 goes for about $200 used and includes following:
  • small 1l form factor
  • i5-9500 (6c) CPU w/ VPro
  • Supports up to 64GB DDR4
  • 1 x 1Gbit Ethernet
  • 1 x Wifi6 + BT
  • 3 x USB 3.2 Gen 2 (10 Gbit)
  • 3 x USB 3.2 Gen 1 (5 Gbit)
  • 1 x USB 3.2 Gen2 Type C (10 Gbit)
  • 1 x nvme slot + 1 x SATA SSD
  • 1 x FlexIO port (small add-in card support for things like serial, vga, usb, etc)
  • 2 x Display Port
Lenovo and Dell have similar models that are comparable. So find whatever is cheapest and most available.
All in all for $200 its more than capable for being a good little desktop
Great comment. I also really like the new AMD mini-PCs you'll see on Amazon for new. The Beelink systems are very nice for the price.

have you had yours a while? the longer term reviews on amazon mention these units dying around the 1 year mark

Wonderful write up, it is crazy what you now can get for half the price of my old machine.
