HP Z640 refurbished workstation
The case will have minor scratching on it.
The HP Z640 Workstation is designed for compute-intensive applications such as complex imaging, CAD, finance, research, and geologic exploration. The Z640 has more options than previous Z-Series systems, the system can be easily upgraded to meet individual needs. Some of the new features include better expandability, increased throughput speeds and efficiency, tool-free component upgrades, and integrated handles. This is one of HP quietest models to date in which HP calls it "Library whisper".
