Sounds like you got a good deal
Yeah, it was a good deal but what really made it was the condition of the PC - it was like getting a new PC from Dell as the previous owner took meticulous care of the PC and kept everything, including all of the plastic slipcovers for the mouse, keyboard, baggies for the documentation, etc...
A quick check shows that there are plenty of deals to be found on Dual Core CPU PC’s for $150, shipping included.
That’s the route I went after my previous PC needed a new MB, then a CPU upgrade, then a Video board upgrade, etc...
You can always tell an oldtimer when they refer to a “card” as a “board” because the old video/audio cards were more like boards due to their size.
Someday, there will be “Mothercards”
