HP Z2 Tower G4 (2020)

Powerful performance for the money, as tested. Highly configurable. Compact for a mid-tower. Quiet cooling fans. Removable dust filters. Standard three-year warranty.

Unlocked CPU in test config (Core i9-9900K) isn't overclockable.

HP's Z2 Tower G4 measures up to the workstation competition and then some. As tested with an Intel Core i9 CPU and an Nvidia Quadro RTX 5000 GPU, it offers solid performance per dollar and quiet operation, not to mention excellent expansion potential.
