I couldn't even give this away.
If you still have that thing, it'd make an awesome whitebox firewall with Astaro or Untangle or pfSense. My Astaro was running on a 939 dualie until last summer when I replaced it with an orphaned Athlon 3800+ AM2 board (which I switched to because it was on a mATX board, lower power/noise, and I could put it in a smaller case).
Works
great.
Before the 939 (which was once my HTPC before it got upgraded to a Core 2 Quad), I had the firewall on my old NForce 2 (the Honored ASUS A7N8X-E Deluxe) with the sweet Barton XP-M 2500+. Now
that was a board. A little finicky, but rock-solid (and still works now), and it'd make those Athlon XPs sing...
Sigh. Those were the days, my friends, those were the days (now
get off my lawn).
Anyway... The 939 would be a good choice for a nice router, if you want to do something with it.
And, if not, I think I have another one in a box somewhere I'll give up. I even might have (though I might have junked it, finally) an old Gigabyte NForce 3 board with an AGP port somewhere. That thing was a rare bird. It was a socket 939 board with AGP. I think they only made like 12 of them.
