Thanks for all you guys for your enthusiasm in your willingness to help me in this endeavor, but I should have checked dimensions before going any deeper into this, I just did some measurements and I can't go over 13.5 inches in width without making myself uncomfortable in that desk, and chances are in the other side of the footrest I will add a narrow drawers unit or a bracket to hang the receiver sideways.
So that makes the search even harder
, but the SB-1000 is within the right width.
Sorry about the cable mess, once is done all of those cables will be cut to length and everything else will be hidden within the cable management
