HP Z4 G4 Workstation | Xeon W-2123 | NVIDIA Quadro P400
The HP Z4 G4 is the world’s best-selling performance workstation, engineered to provide a rock-solid foundation for the 2026 demands of professional engineering and development. This configuration features the Intel Xeon W-2123, a high-frequency quad-core processor (3.60 GHz base) designed specifically for single-threaded performance in CAD applications and stable compute in Linux server environments.
Equipped with 16GB of DDR4 ECC RAM and the NVIDIA Quadro P400, the Z4 G4 is a high-reliability "workhorse" capable of handling 2D/3D modeling, software compilation, and dedicated dev-ops testing with enterprise-grade stability.
Key Performance Features
-
High-Frequency Xeon Architecture: The Xeon W-2123 is optimized for workflows where clock speed is more critical than core count (such as AutoCAD or SolidWorks), while maintaining the reliability of ECC (Error Correction Code) memory support.
-
NVIDIA Quadro P400 Graphics: A professional-grade GPU designed for reliability and driver stability. It provides a crisp, multi-monitor output (Mini DisplayPort) optimized for professional software suites rather than consumer gaming.
-
Front-to-Back Airflow: The Z4 G4’s legendary chassis design features a sophisticated internal layout that keeps the CPU and memory cool under heavy thermal loads, ensuring the system doesn't throttle during long render or compile times.
-
Security & Manageability: Includes HP’s suite of security features, including Sure Start (self-healing BIOS) and a TPM 2.0 module, making it fully compliant with modern corporate IT and government security standards.
-
Tool-Less Serviceability: The interior is designed for rapid upgrades. Changing the power supply, adding RAM, or installing additional PCIe cards can be done in seconds without specialized tools.
Technical Specifications
-
Manufacturer: HP (Hewlett-Packard)
-
Model: Z4 G4 Workstation
-
Processor: Intel Xeon W-2123 (3.60 GHz Base / 3.90 GHz Turbo | 4 Cores / 8 Threads)
-
Memory: 16GB DDR4 ECC Registered RAM
-
Graphics: NVIDIA Quadro P400 (Professional 2GB GDDR5)
-
Storage: NONE INCLUDED (Supports M.2 NVMe and 3.5" SATA)
-
Operating System: NONE INSTALLED (COA likely embedded in BIOS for Windows 10/11 Pro)
-
Chassis Type: Professional Tower
Technical & Institutional Advantages
-
Perfect "Dev Sandbox": The Xeon W-series is highly compatible with Linux distributions (Ubuntu, Fedora, CentOS) and hypervisors like Proxmox, making this an ideal low-cost node for home labs or local development servers.
-
Reliability Over Consumer PCs: Unlike standard desktops, the Z4 G4 is rated for 24/7/365 operation, utilizing high-MTBF (Mean Time Between Failures) components and a high-efficiency power supply.
-
M.2 NVMe Ready: The motherboard features integrated M.2 slots, allowing you to install modern high-speed storage that provides a significant performance boost over standard SATA SSDs.
-
Strategic Value: Acquiring this "Tested-Working" Z4 G4 allows you to deploy enterprise-grade hardware at a fraction of the cost of a new desktop, with plenty of headroom for future RAM or GPU upgrades.
Ideal Applications
-
Engineering & CAD: 2D Drafting, 3D modeling, and architectural design.
-
Homelab & Virtualization: Running lightweight VMs, Docker containers, or Plex servers.
-
Software Development: Compiling code and running local testing environments.
-
Office Power User: A reliable, high-speed workstation for data-heavy Excel work and multi-tasking.
Condition & Quality Assurance
-
Status: Used — Tested & Working.
-
Testing Status: The system has been verified to boot into the BIOS and a Windows PE boot environment. All internal fans, ports, and the power supply are functional.
-
Cosmetic Condition: Minimal wear from professional environment use. Photos are of the actual unit.
-
Hardware Note: This unit is sold without a hard drive. You will need to install your own storage (M.2 NVMe or SATA) and operating system before use.
-
Included: HP Z4 G4 Tower only (Power cable included; no peripherals).
