I'll probably keep the drawer slightly ajar to deal with heat for now, but I am curious about ways I can give off a bit of cooling in the drawer so I can keep it closed.
If there is a coolant system I could run through it, that would be pretty neat.
You could cut out a section of the front panel of the top drawer and add a vent like one of these, google.com/search?q=plastic+white+...
Since you're already drilling holes in it, why not one at either side with a little fan on each to draw air in and out?
Leaving it slightly ajar is probably not enough. You'll want some form of air circulation. Perhaps a small usb fan.
