Adesso AKB-111UB

This is a 60% keyboard running Membrane switches. A wired connection and single-color backlighting round out the spec sheet. A 60% layout maximizes desk space but drops arrows and F-keys to layers. Switch feel is personal; try the switch type before committing if you can.

Its $14.99 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. Support and warranty service run through Adesso, with terms that vary by region. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
