My T4 and HD702E display came with some nice perspex mounting plates so it all goes together nicely.
I then use a small cheap Chinese sourced CNC mill to cut out a front panel from 3mm acrylic and then use 3M VHB tape to secure it to the front panel. Works great. The attached image shows how it looks. (this is a prototype. the final one will have the text engraved and paint filled)
