Joe, There isn't enough information supplied to make any solid recommendations. For example how much power is A LOT? Also, where in the assembly is this PWB? Is it in a card cage or mounted to a chassis frame? What is the operating environment? What type of devices are you mounting (TO-3, TO-220, bare chips, etc)? Answers to these questions will help you decide on an approach.
