About This Product
Overview
The HP Z840 Dual CPU Workstation Barebone Tower is built for users who need a flexible foundation for a professional workstation build. As a tower chassis with dual-socket support, it is designed to accommodate Intel Xeon E5-2600 v3 and v4 processors in an LGA2011-3 platform, making it suitable for custom configurations where compute capacity, memory expansion, and add-in card support matter. Because this is a barebone system, it provides the core chassis and platform architecture without CPU, RAM, or storage installed, giving buyers the freedom to configure the system around their specific workload requirements. For IT teams, resellers, and system builders, this kind of platform is especially useful when a tailored workstation is needed for design, engineering, content creation, virtualization, or other demanding professional tasks.
Performance & Scalability
With support for dual Intel Xeon E5-2600 v3/v4 CPUs and DDR4 ECC registered memory, the Z840 platform is designed to scale with heavier workloads and larger memory requirements. The dual-socket layout allows for balanced processing resources, while ECC memory support adds an important layer of reliability for environments where data integrity is important. PCIe 3.0 expansion slots provide room for graphics cards, controllers, or other expansion hardware, helping the system adapt to changing needs over time. This makes the chassis a strong starting point for a workstation that may begin with a modest configuration and later be expanded as project demands grow. The platform’s architecture is well suited to users who want a workstation that can be built to match performance goals rather than relying on a fixed factory configuration.
Storage Flexibility
The HP Z840 barebone tower supports NVMe, SATA SSD, and HDD storage options, giving builders flexibility when planning both speed and capacity. NVMe SSDs can be used for fast system responsiveness and application loading, while SATA SSDs and hard drives can be added for broader storage needs, project files, or archival data. This mix of storage compatibility makes it easier to design a workstation that fits a specific workflow, whether the priority is quick access to active files or larger-volume storage for ongoing work. For buyers sourcing a platform for custom deployment, the ability to choose the right storage mix is a practical advantage that helps align the system with real-world usage requirements.
Why Choose This Product?
This HP Z840 barebone workstation chassis offers a dependable starting point for building a professional dual-CPU system with room to grow. It combines dual-socket processor support, ECC memory compatibility, PCIe expansion, and flexible storage options in a tower form factor that is well suited to workstation deployments. Because the system is sold without CPU, memory, or storage, it is ideal for buyers who already have compatible components or want to source parts separately for a custom build. For organizations and technicians looking for a platform that can be configured around specific performance, storage, and expansion needs, the Z840 provides a practical and adaptable foundation.
Why Buy a Refurbished Products?
Refurbished enterprise servers offer enterprise-grade performance at a fraction of the new price.
Up to 70% Cost Savings
Refurbished R650xs units deliver identical hardware capability to new, at significantly lower upfront cost — freeing budget for CPUs, RAM, and storage.
Fully Tested & Verified
Every unit undergoes comprehensive hardware diagnostics before dispatch. POST tests, burn-in, memory checks, and power supply verification are standard.
Immediate Availability
Unlike new enterprise servers with lead times of weeks or months, refurbished stock is ready to ship within 24 hours of ordering.
Same Performance
The hardware inside the R650xs performs identically whether purchased new or refurbished. The 3rd Gen Xeon platform, PCIe Gen4, and iDRAC9 are unchanged.
