Yes, they are not the fastest, think 2 Gig Celeron with 512Meg ram but the one I have on the coil winders works fine with the SmoothStepper so this should as well.
Not sure where to put the computer though, in the pic its on top of the sliding door and it seems fine there, door actually slides better with the extra weight, the other option is make a wee arm to suspend it from over the headstock end. Might go for the latter as that will allow it to be a bit higher and have a keyboard below with a MPG.
Lots of I/O on the computer as well but sadly wont use much of it on this build.
