I have yet to build my kegerator (it's on my brewery roadmap, though), but I think the question you ask depends on what design kegerator you desire. If you look around this forum you will find designs that use upright freezers (taps in the door), chest freezers with collars, chest freezers with tap towers and mini-fridges. All have positives and negatives associated with them.
Your 5-keg requirement probably eliminates the mini-fridge, so choose one of the other general categories and then there will likely be some feedback from folks that have used one model or another. My sense is that the freezers of the world are largely similar in quality, though there may be some minor differences in where the coolant lines are routed that could drive the layout of your design.
Sorry I can't offer more specifics, but when's you've chosen a design category the knowledge on these pages will likely flow freely.
