Inventory Form Hardware Inventory You need an inventory of all existing equipment. You might want to use a template or one of the many software applications available for compiling hardware inventories. Be sure to include as much detail as possible, including serial and model numbers, locations of the equipment, and any exact specifications (hard drive sizes, CPU speeds, RAM, versions, licensing, and so forth) you can find. If gathering this much information isn’t possible at this time, be aware that a complete hardware and software inventory should include this information.
