turning a stand up freezer into a grow room

i have a stand up freezer that has a leak in the cooling system. the repair man said it was cheaper to buy a new one then spending the time finding the leak. so now i have the idea of making it into a little grow room. does anyone have any experience with this. i'm just wondering how much work it would take to convert it.

Actually it's not hard. Modify the fridge like u would a box. Mb tear off the insulation. Good luck m8
