For the size of the inside of the cooler, don’t forget about the tap height!!
I didn’t account for it and I had to do some last minute hacking on the inside to make room for a slim 1/6 for my Sam Adams keg (which was the whole reason for building the kegerator in the 1st place) and it really spoiled the insides of my cooler. It still functions, but I am stuck now with my configuration of kegs and can’t use all three taps that I was planning as a result.
Here’s a quick link to my photo Album
Also, for keg size, a handy guide can be found here…

Draft Beer FAQs
With Homebrewing, count on wanting to get into look at your brew alot so you’ll want ample space to manuever.
Only two things affect the distances needed for behind the bar…
…and don’t be offended, Matty, because you asked and your screen name demands that I mention this…
1. Your Size.. the size of the bartender is pretty crucial, you certainly don’t want to build something that’s going to be a hassle to work behind.
2. The size of your room
Other than that, ther are no real guidelines
I’d do a test run in your kitchen.
Stand in front of one of the counters and actually see how much room you need behind you to get a keg into the cabinets below.
Good Luck!!
