Overview
Routing high-throughput enterprise I/O through a single-socket footprint, this tower platform pairs Intel’s LGA 1700 architecture with a dedicated full-height PCIe 5.0 x16 slot alongside three PCIe 4.0 x4 expansion slots. Compute configurations accommodate Intel Xeon E-2400 and Xeon 6300 series processors up to an 8-core ceiling and a 95W TDP limit. Memory routing across two channels supports up to 128 GB of TruDDR5 ECC UDIMM across four slots, with operating speeds constrained to 4400 MHz to maintain multi-bit error-correcting stability under sustained processing loads.
Mechanical versatility centers on a convertible chassis that transitions between a standalone pedestal tower and a 4U rackmount deployment. Storage expandability is exceptionally dense for an entry system, accommodating up to 16x 2.5-inch hot-swap drives, up to 8x 3.5-inch simple-swap or hot-swap bays, or a split configuration of 8x 2.5-inch and 4x 3.5-inch drives, complemented by dual 5.25-inch media bays for optical or tape backup options. Dedicated boot resilience is managed via dual M.2 bays supporting form factors from 2242 through 22110, though these slots remain strictly constrained to legacy SATA transfer speeds rather than NVMe protocols.
Thermal and acoustic containment is engineered specifically for edge offices without dedicated server rooms, producing a whisper-quiet 30.5 dBA at idle, 33.2 dBA under typical 100% CPU TDP operating loads, and peaking at 35.9 dBA under full stress. Power consumption scales from 141 W at idle to 409 W under maximum load. Out-of-band management is handled by the integrated Lenovo XClarity Controller 2 (XCC2), providing hardware health monitoring, remote provisioning, and proactive firmware maintenance without requiring an operating system presence, cementing its reliability for remote branch administration despite single-GPU limits.
