Yeah, going back over it, i still like my method the best, Jerm. I just checked on Craigslist and you can find Slim form factor Business class PC's for $200-$250 all day long, with 3.4GHZ I5's.
They may not be 4460's, but a 3.4GHZ I5, along with every other salvagable part including the OS for $200 is nothing to sneeze at, especially on a budget build. Going that route, you can easily put together a $1,000 PC for $500.
Search CL, find one of those machines, call the guy up and find out exactly which model I5 is in it. Most likely, the processor will be worth almost $200 new, as most I5's seem to fall in that $150-$250 range.
You simply can't beat $200 for an I5, RAM, MoBO, OS, HDD and an Optical drive. And then just buy yourself a PSU, Video Card, Case and some more RAM and throw the rest away.

Just do your due diligence and find out exactly what's in the machine. If you take your time and look thoroughly you can find a diamond in the rough. And with the free Windows 10 upgrades for the OS, you'll be golden.
