David,
You may be over thinking things....
Consider an older s/h laptop which can run your mount (NEQ6/EQMod?), CdC (for acquisition), PHD for guiding and finally your camera control (AstroArt) connect this via a powered USB Hub (leaves only one USB back to the laptop) and then use Teamviewer (via WIFI or direct Cat5 link) to a computer inside. Once set-up you can close the lid of the laptop - no light interference.
I even added a Shoestring dongle to the JMI focuser on the C11 for remote focusing.
I have three cameras on the go - DMK51 on an electronic finder, Lodestar for guiding the spectrograph and ATiK 314L for spectral imaging
