Adding a touchscreen on the case and making it run is a little bit of bling- but not to useful- especially when you discover that getting two displays from a core is not supported and will be a lot of development to make work.
I have implemented a touchscreen on the core- its in the basement and not used for media normally- and can give pointers if anyone is interested. But the normal approach is to use an external device.
This sounds fairly interesting for me - I'm want to place the cores in a 19" rack in the garage. Does anyone have any different suggestions for the display for the core? My idea so far will be to use an IP KVM, but I don't know if this is usable during installation of the OS.
