Nice find! @Mat_Helm
Was just about to click the checkout button on a lesser model ($41 with no HDMI or USB 3.0) when I did one last search and found this one…
@Peter_Fouche1 Well, I have a Athlon II 260 CPU already (comparable to a Intel E6700) and a stick of 4g DDDR3 1333 ram. Many many power supply’s, old cases, HD’s and CDroms, so… $51.54… lol 
Shame my Toughbook doesn’t have a parallel port…
I meant to add that the bios on this board allows for using just one core of the CPU (which I’ve read helps latency). And I have a few old video cards to choose from that I can add (which I also read, helped with latency)…
If I remember right, 2meg a sec. But I get my megs, K’s n Gig’s mixed up these days so… ;p
Now just need to decide on the best breakout board. Am approaching this from 2 directions. Parallel and Arduino. Will probably go with and all in one setup (parallel port wise) and some nema 17’s. Then upgrade later with independent drivers for each motor. Would luv to do it all via arduino. My Chinese vinyl cutter/plotter is USB driven and works great.

Here’s my $5 thrift store PC running LinuxCNC
Yeah, ugly desktop, I know. It usually just looks like this
It is an HP a6130n which has some kind of an AMD CPU in it. 2.5 GHz dual core as I can recall. I haven’t tried to isolate the cores in it yet either. I’m good with the speed it does now.
I’ve run that latency test, but the first time I read anything but the numbers was just now in your pic…lol You would think the test itself would run operations to max out the PC for the test…
@Mat_Helm You have to bog your system down yourself. Here are some tests run
