I feel not comfortable at the ML of a board to ask for an other board.

I'm looking for an "interresing board" that comes with a case and a PSU.
Probably I looking for a printserver, a broadband router or
an wifi base station that has the documentation how to hack it.

Any links to such boards with case and power supply unit?
