ISA motherboards are a good idea when a solution does not require a large number of ISA slots. For those situations, we carry a robust selection of ISA motherboards. ISA motherboards are the perfect solution for smaller ISA requirements as they are save money in several ways. First, by using an ISA motherboard, you can generally get away with a smaller rackmount or tower chassis. Second, rear-mount power supplies, which are more cost effective, can be used custom servers with ISA motherboards. Third, the ISA motherboards are less expensive than a SBC/Backplane combination.
