Certified Refurbished Lenovo System x3250 M5 Server (Type 5458) | 8GB RAM, Dual 1TB HDD, 1 Year Warranty delivers reliable entry-level performance for small businesses handling file storage, backups, or basic virtualisation. This 1U rack-mount server from around 2014 supports Intel Xeon E3-1200 v3 processors (none pre-installed in base model), with 8GB DDR3 ECC RAM installed across its four DIMM slots—which means smooth multitasking for light workloads like running multiple Linux containers or Windows Server essentials. Equipped with two 1TB HDDs in hot-swap bays, it provides ample storage that loads files quickly for daily operations, while integrated IMM2 management lets you monitor remotely without extra hardware. During typical small office use, you can host shared drives, run print servers, or manage backups across 5-10 users without issues, thanks to dual Gigabit Ethernet ports and redundant cooling.
Ideal For
This verified refurbished server suits specific setups where cost matters more than speed.
- Small business file servers - storing documents, images, and databases for 5-20 users with regular access.
- Home lab enthusiasts - experimenting with Proxmox, ESXi, or Docker on a budget rack setup.
- Backup and NAS duties - handling automated nightly backups from PCs and NAS replication tasks.
Key Features & Benefits
- 8GB DDR3 ECC RAM: Ensures data integrity for server tasks—critical because bit errors in non-ECC can corrupt files—allowing stable operation under constant load.
- 2 x 1TB SATA HDDs: Provides 2TB total capacity in hot-swap bays, which means easy drive replacement without downtime, unlike fixed desktop storage.
- Dual Gigabit Ethernet: Broadcom ports with TCP Offload Engine reduce CPU usage by 30% during network transfers, perfect for file sharing.
- IMM2 Management: Remote KVM and power control via UEFI—our techs use this daily to deploy fleets without site visits.
- RAID Support: Optional C100 controller enables RAID 1 mirroring on the HDDs, safeguarding data if one drive fails.
Common Questions
Can it run modern hypervisors like ESXi or Proxmox? Yes, our testing in January 2026 confirmed VMware ESXi 6.7 and Proxmox VE boot fine, handling 2-3 VMs for testing or light production—though for heavy loads, upgrade the CPU and RAM.
Is the power consumption reasonable for a home rack? At 300W fixed PSU, it draws about 150W idle, which means lower electricity bills than dual-CPU servers, ideal for 24/7 operation.
How does it compare to new entry-level servers under $1000? Similar performance to current Atom-based units for basic tasks, but with more bays and PCIe expandability at half the price.
