Why Buy a Refurbished HP Z Workstation?
HP Z workstations are engineered for extended product cycles — HP typically offers 5+ years of driver and BIOS support for each generation. A refurbished Z4 or Z6 purchased today will continue to receive security updates and remains compatible with the latest versions of professional software well into the future. Combined with CompuWyze's full inspection and testing process, you get a machine you can depend on from day one.

Frequently Asked Questions
What HP Z workstation models does CompuWyze stock?
Our range includes the HP Z2 G4/G5 (small form factor and tower), HP Z4 G4, HP Z6 G4, and HP Z8 G4. We also carry ZBook mobile workstations periodically. Stock changes frequently — contact us if you're looking for a specific model or configuration.
What is the difference between the HP Z2, Z4, Z6, and Z8?
The Z2 is HP's entry-level workstation, ideal for office professionals and light CAD users (single Core i5/i7/i9 or Xeon). The Z4 steps up to Intel Xeon W processors and adds more PCIe expansion. The Z6 supports dual-socket configurations with two Intel Xeon Scalable processors and quad-channel memory. The Z8 is HP's flagship — dual Xeon, up to 3 TB RAM, and maximum GPU capacity for the most demanding HPC and AI workloads.
Are HP Z workstations good for video editing?
Excellent. HP Z workstations are Adobe Creative Cloud certified, and many units support high-bandwidth internal storage (M.2 NVMe + SATA SSD RAID) and professional GPU cards optimised for GPU-accelerated rendering in Premiere Pro, After Effects, and DaVinci Resolve. The Z4 and above are particularly popular with video production studios.
What warranty comes with a refurbished HP Z workstation?
All HP Z workstations sold by CompuWyze carry a 12-month return-to-base warranty. If a fault arises, we cover all parts and labour at no cost to you. Extended warranty packages are available — please contact us for details.
