The HP Z420 Workstation is a reliable, professional-grade single-processor workstation in a convertible minitower form factor. It’s designed for engineers, designers, content creators, and professionals who need stable, expandable performance for CAD, 3D modeling, rendering, video editing, scientific simulation, and other demanding workloads. With support for Intel Xeon E5 processors, ECC memory, flexible storage and I/O options, and a chassis built for easy upgrades, Z420 offers a balance of performance, expandability, and value — making it a popular choice for workstations in small studios or departmental environments.
Support for Intel Xeon E5 (E5-1600 / E5-2600, v1 and v2) processors for strong, workstation-grade CPU performance.
Up to 64 GB DDR3 ECC/unbuffered memory over 8 DIMM slots — suitable for heavy multitasking, large CAD/3D/engineering workloads.
Wide storage flexibility: multiple drive bays supporting SATA, SAS, SSDs (SATA and PCIe/NVMe depending on add-ons), enabling large and fast storage setups.
Professional graphics support — compatible with a broad range of GPU cards: from basic 2D (NVS) to entry-level 3D (Quadro/FirePro) up to high-end 3D and GPU-compute cards (e.g. NVIDIA Quadro K-series, AMD FirePro/W7000, even Tesla GPUs for compute workloads).
Good expansion capability — multiple PCIe slots (PCIe Gen3 x16, x8, etc.) plus legacy PCI slot, enabling GPUs, RAID/SAS controllers, additional NICs, or other expansion cards.
Flexible RAID and drive controller support, with integrated SATA controller offering RAID-0/1/5/10, and optional SAS controllers for enterprise-grade storage configurations.
Convertible minitower design with easy internal access for upgrades or maintenance, making it user-friendly and serviceable.
Wide OS compatibility — supports Windows (various versions) and Linux distributions (with HP Linux Installer Kit or SUSE/Red Hat) out of the box.
