Chassis for dense 2U storage
The Supermicro CSE-826BE1C4-R1K23LP is a 2U rackmount chassis designed for storage-heavy workloads. It holds twelve hot-swap 3.5-inch bays and four hot-swap 2.5-inch NVMe bays on a 12Gbps expander backplane. Redundant 1200W Titanium power supplies with PMBus 1.2 deliver 96%+ efficiency. Seven low-profile expansion slots support add-in cards.
Verify motherboard size and backplane cabling
Confirm the motherboard measures no more than 12 by 13 inches for E-ATX fit; the rear 2.5-inch option is only supported with a 12 by 13 board. Ensure the system provides enough 12Gbps SAS cables or a compatible HBA to drive the expander backplane. Check that the 8cm PWM fans meet the thermal design of the chosen processors, rated up to 205W each. Validate rack depth clearance for the 25.50-inch chassis length.
Replaces smaller 2U or non-redundant enclosures
This chassis upgrades from 2U units limited to eight 3.5-inch bays or lacking NVMe hybrid slots. The jump is worth it when a single node must serve both capacity and latency-sensitive tiers without a separate JBOD. It also supersedes builds using single power supplies by adding Titanium redundant units. Buyers needing full-height cards or more than seven low-profile slots should consider a different form factor.

Questions about this item
Does the chassis include the 12Gbps expander backplane and NVMe cables, or must they be purchased separately?
The chassis ships with a 12Gbps 12‑bay expander backplane and supports 4×2.5″ NVMe drives; NVMe cables are not included.
Should I choose the 12×3.5″ SAS/SATA bays with 4×NVMe hybrid layout or add the optional rear 2×2.5″ bays?
The 12 front bays handle 8×SAS3/SATA3 plus 4×NVMe; add the rear 2×2.5″ bays only if the motherboard is 12″×13″ and extra OS drives are needed.
What does the redundant 1200W Titanium rating mean for actual power delivery in a dual‑CPU build?
Each 1200W supply delivers 96%+ efficiency with PMBus 1.2 monitoring; the pair supports up to 205W dual processors plus all drives and fans.
