48U is a common rack height sold for data centers. 48U = 48 Rack Units on your Mounting Rails = 84" of rack mount space available. Please note that actual internal and external height vary depending on the server cabinet manufacturer. Depending on your application, requirements, and space limitations; a smaller, more specialized cabinet may be best for your needs. Though it may be intuitive to think that a smaller rack would be less expensive because of less steel being used, server cabinets in the 48U height range are mass produced and therefore usually have far less production cost.
