Undercounter fridge

I bought a 4 tap T tower on eBay and was wondering if there is an undercounter fridge that will hold 4 ballocks other than commercial bar fridge.

I have looked into this and found that under-counter fridges will hold 3 ball-lock or pin-lock kegs. I found these at Beverage Factory
