Choosing the HP ProDesk 400 G4 Microtower PC

This configuration lists 4 GB of memory and 500 GB of storage. Memory supports active applications; storage holds software and files. Check upgradeability separately, because a capacity figure does not establish whether either component can be replaced.

Compare the specification with your intended use and read the original reviews for performance, comfort, reliability and other qualities that a specification sheet cannot establish.

Before choosing this desktop-pc

  • Budget for monitor, keyboard, mouse, cables and operating system if absent.
  • Match processor, memory and graphics to named applications.
  • Measure desk and ventilation space, including cable access.
  • Confirm monitor outputs, resolution and refresh support.
