under my dining table as i have an atx tower case, dont have a proper desk setup any more and we have a 6 person rectangle, so my tv, speakers, k/b & M are at the end which faces a wall, we only have 4 chairs and im basically in the corner, i quite like the setup as its just a case of unplug the tv and take it off and its out the way and im not in the way of every day life.. when i had a cube it was on a sideboard setup i had, but i would only have cubes/htpc on top or on shelves, not towers anymore.
