Thanks for writing.
As a budget solution, you can potentially use the LUXv2 as an all-in-one unit for a demo, private/personal, or beta testing purposes.
However, this is NEVER recommended for a custom installation. The LUXv2, since it runs Windows Vista/7, does need updates/reboots during these processes, the automation side would obviously no longer work.
In general, if vAutomation/CQC is needed, we recommend starting off with a FireServer for the storage & vAutomation processing, and then adding in an extender for AV playback. This dramatically increases your automation stability since the server never needs to be rebooted.
If you want to use your own touch pads, you can do that if you wish. Of course, you'll need to create your own templates (since screen sizes are likely to be different) and provide your own support as it is non-VidaBox hardware.
