The exhaust will prove useless unless there is an inlet for fresh cool air to come in at. Cut a small inlet and you should be good if you aren't using too small of a pc fan, or using too hot of lights. You dont even need a fan on the inlet as the pull from the exhaust will draw in new fresh air from the inlet naturally if it is pretty air tight of an enclosure. Keep in mind that you want the exhaust up higher in the enclosure and the inlet down low on the opposite wall that the exhaust is on. This will help with full exchange of air in the enclosure when the exhaust fan is on.
yup I do actually lol.the plastic on the inside is quite thin.I cut mine with a utility knife,pulled that plastic out then cut away the insulation.(I didn't want to hit anything,as I wanted the fridge to keep working).using a 1"-2" putty knife I kept sinking that thru the insulation careful and dug it out.you don't need to be that careful if you don't plan on running it.once the insulation is out,that fridge "skin" is thin as shit.you're going to have to think creatively if you're going for a perfect hole lol
It's very light now that u mentioned it, for some reason I thought I'd had to cut threw layers of crap like a safe. Don't ask how I know that. Anyway I'm a try your cheaper version before I go drill shopping thankx.
