Need some help with wine cooler incubator DIY

I just bought a used wine cooler and plan on converting it into an incubator. Does anyone have some plans or experience in converting the wine cooler into an incubator? Would like to get an idea of what I can do to the wine cooler, where to drill holes and such.

For my wine cooler incubator, I basically removed the refrigeration unit first. Mine had a light and I just left it in working condition. As far as drilling holes, I used the existing hole in the back where the fridge control unit came through. I ran my power cord attached to flexwatt and my temp probe through this. The only extra hole I drilled was near the bottom side and ran a power cord in for a 4" CPU fan for circulation. I used 11" wide flexwatt taped to the back wall(inside of course) from near the bottom to the top of the unit. So far this unit has worked perfectly. Good luck!
