HP 320K

A TKL keyboard running Membrane switches. A wired connection and single-color backlighting round out the spec sheet. Switch feel is personal; try the switch type before committing if you can. TKL frees mouse space without sacrificing the function row.

Its $12.99 price tag places it squarely in budget territory. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total. Warranty coverage follows HP's standard policy — confirm regional terms on the listing. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
