Hi Steve,
Thanks for the links, look everywhere but couldn't find them.
I haven't seen the inside of the endplates till you give me the link's, now I see that are some tracks on the back endplate, that is making my idea more difficult.
My idea was to put two HL2 in an 19" rack box, from 2U to 4U, or something like 310x280x80/120mm inside dimensions, and pass all the front connections to the back, leaving only one power button on the front and the leds, but I wasn't expecting the track's on the back panel, so I've to rethink my approach.
