I'm behind getting my 200 series build thread started, so I figured I would post some of the design details for the drawers here. Several of the ideas can be used in any box.
The first concept is how to place the drawer fridge in a moveable drawer. The fridge doesn't pull much power, but I still wanted to use 12 AWG wire for safety and efficiency. This is too thick and inflexible to bend over itself above the drawer slides, so I need another solution. I purchased a 3x12 gauge coiled power cord from Walmart (cheaper for the same product than Amazon). I cut off the ends and secured it to the box frame in the back, and extended it through a hole in the rear of the drawer, where I trimmed and secured the other end.

You will probably notice the wire along the top of the cord. I needed the drawer to open and close with ease, but the cooked power cord does not spring back very quickly and also tends to sag. So I purchased a Key-Bak retractable key chain holder from Amazon. It uses a Kevkar cord and has enough spring tension to hold up the power cord and keep it linear during extension and retraction. I connected it to the power cord with zip ties.

Just in case it still hangs up, I put a small hinged access just large enough to reach through above the power cord where the drawer meets the frame in back. If the power cord ever gets stuck between the drawer and frame, I can reach in an fix it quickly. The photo below is with the drawer completely closed. I will try to get one with it open as well to show the power cord.
