Case / Power

Fanless Case

Optimised for Micro-ATX and Mini-ITX Motherboards

Designed to support a diverse range of common Micro-ATX and Mini-ITX form factor boards with Intel® LGA1851/LGA1700/LGA1200/LGA115X sockets.

Supports Intel® Core™ (8th-14th Gen) & Core™ Ultra (15th Gen) processors up to 35W TDP.

Superb Passive Cooling

High-performance aluminium thermal module and dual copper heatpipes transfer heat efficiently from the CPU to the external aluminium fins, increasing surface area for rapid dissipation into the surrounding air without any moving parts.

Front and Rear Panel Layout

Features USB 3.2 Gen 1 (5 Gbps) Type-A ports and low-profile PCIe slots for expanded connectivity.

2U Rack-mountable Case

2U profile height, rackmount case with convenient pull-out handlebars. Fits in standard 19" server racks.

Perfect for enterprise server, embedded computing, industrial control, audiovisual, medical equipment, or NAS/RAID applications.

Hot-swappable Drive Bays

Supports up to four 2.5" SATA SSDs/HDDs (up to 9.5mm height) with designated, lockable, tray front flaps for easy, tool-less mounting with hot-swap capabilities.

Silent Reliability

Completely fanless design eliminates noise and reduces mechanical failure points, ensuring reliability under continuous operation.

Ideal for applications sensitive to sound and vibrations.

Low-profile Expansion Slots

Supports up to four low-profile PCIe cards.

This list is maintained on a best-efforts basis; see the version date on each list. New and revised motherboards appear constantly, so it may be incomplete or out of date. Omission does not mean a board is incompatible. The list indicates mechanical and thermal suitability for this product only. Whether a motherboard supports a given CPU, and any BIOS version required, is determined by the motherboard manufacturer; please check their CPU support list.

Case compatibility is determined by the supported socket(s), maximum processor TDP and form factor stated in the product specification. Motherboards within those limits usually fit, but layout can still prevent installation, including heatsink keep-out areas, VRM height, connector placement and M.2 placement. TDP indicates thermal capability, not guaranteed sustained performance. Ambient temperature, workload, placement and BIOS power limits all affect a fanless system.

If in doubt, contact Akasa before purchasing, quoting the exact motherboard model and intended CPU.
