This is for generic pieces of computer hardware that don't have more specific infoboxes, such as hard drives, motherboards, CD-ROMs etc. It should not be used for hardware such as CPUs that have their own specific infoboxes. External hardware should not use this box either.

All fields, except 'name', are optional

The numbered attributes mean that there is allowance for multiples. The via attributes range from via1_1 to via3_9 where the first number corresponds to the appropriate connection number and the second number is the position in that connections 'via' list. For each connection (via_1, via_2, or via_3), there can be up to 9 connectors, via#_1 through via#_9.
