Hi Darren. A kegerator is worth the effort. My Mark 1 kegerator built from a refurbished fridge off of Gumtree had taps in the door. I had some issues with the door moving the beer lines and eventually loosening them.
The compressor eventually died on the Mark 1 and I put my Mark 2 kegerator together with new fridge and a beer tower. Photos below. Five holes in top - one for the lines and four for the bolts to the tower. The set-up is serving me well.
With whatever set-up you go with, be sure to get the beer line length correct. Good luck!
