initial script test results are in . A few tweeks will be needed . The cooling fan is one of them. as in it just needs to stay on. LOL

last bit of lat. file
so far very promising. I will do some more testing though to to see what It can do.
I also want to see if I can get the CPU temps down
Hey tommylight how does it compare to the full size or SFF 9020 ?

Yes, not much has changed !
I never bother disabling anything on PC's with such good latency, they do not have parallel ports so why bother.
The latency is very good as such, wire in the Mesa and move something !
BTW, fan speed on such PC is in hardware or power sections sometimes labelled as noise something or another, or quiet/normal/performance.
