So let's start at the beginning.
In the Man Cave, I had a Chromebox.  The purpose was to have something that I could do web searches and display information that I needed for my projects.  But I was finding that I really needed something more. 
I was able to pick up a Raspberry Pi 4 4GB and got a case with a fan.  According to everyone, it would work as a full desktop PC.  But it wouldn't be a speed demon.
That was fine.  I didn't need a powerful PC for the Man Cave.  Just something that would do some light weight things.
The bad news: YouTube was not "light weight" enough for the Pi4.  8(
So the Pi4 is now a project box.  It will get a new OS install at some point.
Today, I visited the Junk Store (what other people call Valley City Tech Store) and picked up an HP EliteDesk 800 G1 (small form factor PC).
Core i1-4360u, 3.70Hgz, 500 GB HD, 8GB RAM.  It includes a DVD writer, sound, NIC and 10 USB ports (some USB3!).  Only $120 (including the Display Port to HDMI cable).
My only disappointment is that it's supposed to have wireless, but it doesn't.  I had to use the UDB WiFi dongle that I had in a really old PC that's about to go to Goodwill.
Interestingly, that's the same amount that I paid for the Pi4 and extras.
