The financial controller says I can buy a kegerator/keezer….

Anybody got any good recommendations.

I'm kegging in 2½ gallon pepsi and coke kegs, so want to be able to serve two or three at a time. I'm happy to DIY if you just have good suggestions for specific equipment for conversions.

A 7 cubic foot will do 4 kegs with no issues I think. Plus the hump can hold a 10lb CO2 as well so it's all enclosed.
I build a 2x8 collar and lined that with some rigid foam insulation and ran the tap shanks through.
I was using the 5gal pepsi kegs.
You using the short kegs, only reason for a collar would be easier to feed taps out.
Easily can do picnic taps as well to start to determine where you want your taps.
I have used the cheaper ST1000 (or STC1000 - whatever they are) for temp control and most recently I use one of the inkbird that have the plugs already on them - easier as there is no wiring at all.
When I did my first and used the STC1000, I moulded the temp controller into the lid of the keezer so it was pretty sleek, but a bit of effort.

My recent keezer is a 9 cubic foot I believe and I can get 6 kegs with no issue and have a hump to store bottles/cans.
I have a fan rigged up inside to circulate air.
They do get damp. I've used the re-chargeable damprid things before - now I just mop up the moisture when it gets too much.

Good luck!
