4U rackmount chassis for dense builds

The Silverstone RM44 is a 4U server chassis that fits Micro ATX, ATX, Mini ITX, EATX, SSI EEB and SSI CEB motherboards. It is built for industrial racks or high-end home systems that need dense expansion in a standard rack footprint. Vertical or horizontal mounting gives deployment flexibility.

360 mm radiator headroom and GPU length

Front intake accepts radiators up to 360 mm with three 120 mm fan positions, while two 80 mm side fans push air rearward. CPU coolers up to 148 mm tall clear most tower designs. Graphics cards up to 424 mm long and power supplies up to 255 mm deep fit without interference.

Eight PCI slots and front USB Type-C

Eight full-height PCI expansion slots support multi-GPU or add-in card arrays, and a card retainer prevents sag. Front panel includes one USB Type-C port and an anti-theft lock. Sliding rail holes simplify rack installation, though depth-constrained cabinets may limit rail travel.

Questions about this item

Will my existing EATX motherboard and 360 mm radiator fit in the RM44?

Yes. The chassis accepts SSI-EEB and EATX boards and the front mounts radiators up to 360 mm.

How do I confirm the front-to-back airflow is working once the system is built?

Check that the two pre-installed 80 mm rear fans exhaust while the three 120 mm front fans or radiator fans pull cool air through the star-crossed vents.

Does the RM44 ship with rails and a USB Type-C cable for the front port?

Sliding-rail mounting holes are built in; rails themselves are not included. The front USB Type-C port connects to a motherboard header — cable not supplied.
