I think the Pace DS-830 series decoder is marketed as a "single chip" satellite decoding solution, must be one of those system-on-a-chip IC that integrates as many things as possible. There will still be some peripheral chips, but until someone voids his/her warranty and opens up his/her Byond/Pace DS-830NA and posts pictures of the circuit board, then only we can be sure of the design.

Speaking of opening up the decoder, I noticed the screws are not the regular allen key screws, but some multi-angled "security" screws, I think it is still possible to get those 30-in-1 screw driver set that has this combination. Take a look at the close up photos of the rear and observe the type of screws used...


Edit: One more photo to show the screws at the side...
