Husky Steela beer cooler that I have modified with a pc fan. When I used it cooling thing took forever and sometimes, depending on where you placed things, never got cool at all.
so I drilled a very small hole in the top of it to feed the two small fan cables through to the inside of the fridge and mounted a PC fan. When on and in use this will chill anything to ice cool with in hours and keep it that way even on the hottest of days.
If you dont like the idea of the cables poking out etc etc, then pull em out and blob on a small bit of silicon.
There is also a dint in the bottom corner at the back and top.
£30 collected, I might able to deliver too, depending on location.
