Pictures/Ideas for room perimeter cable chases.

Hi all, I'm getting down to the details of my studio rebuild and was about to tuck some cables between the hardwood floors and the wall and then cover with molding when I realized that I should think towards the future and build easy-access floor mount cable troughs around the perimeter of the whole room so that I can easily lay and swap cable to the machine room as well as just have everything neat when I add 5.1 and need to wire the rear speakers. I figure I just need to build boxes a few inches wide and a few inches deep with a hinged lid but I'm having a hard time thinking of how to do it and have it look nice. Anyone done the same thing and have some pictures that they would like to share? I'll attach one of my room as it is right now. Machine room will be through the wall behind the couch so I'm looking to build from the console to the wall behind it (picture isn't clear, but it's actually two angled walls), and then around the perimeter on both sides and behind the couch. Thanks, Ryan
