Our buddies at iFixIt have torn down the Logitech Revue Google TV box and found what amounts to be a mini computer powered by an Intel Atom CE4150 1.2 GHz processor. Oddly enough, for a device with no storage space, it contains 5GB of NAND flash.
Their final take:
Opening the case is super-simple — only 4 screws and a bunch of clips stand in your way.
Only standard Phillips screws are used.
Daughterboard connectors easily disconnect from the motherboard sockets.
The fan is very easy to replace, should it ever fail.
If you have to replace anything on the motherboard, you have to replace the entire board.
