Compact 1U rackmount for Mini-ITX builds

The In Win IW-RF100S-S265 is a 1U rackmount server chassis designed for Mini-ITX motherboards measuring 6.7" x 6.7". It ships with a single 265W power supply and meets the Standard EIA-RS310D specification for 19" rack mounting. The short depth of 9.84" suits space-constrained server rooms or edge deployments.

SGCC steel body with tool-free drive cages

The chassis uses SGCC steel construction and includes two NMB 40 x 28 mm PWM fans, with support for up to three fans total. Drive installation is tool-free: the cage accepts two 2.5" drives and two 3.5" drives, with an optional configuration for four 2.5" drives. Front I/O provides two USB 3.0 ports alongside power, reset, and status LEDs for power, drive activity, and network.

Verify Mini-ITX board and 265W power budget

Confirm the motherboard is Mini-ITX form factor before ordering, as larger boards will not fit. The included 265W power supply sets the total system power limit, so calculate CPU, memory, and drive draw accordingly. The 20" friction slide rail kit fits standard 19" racks, but rack depth must accommodate the 9.84" chassis length plus cable clearance.

Questions about this item

What does the Standard EIA-RS310D feature mean for rack mounting this 1U chassis?

It confirms the chassis meets the 19-inch rack standard, so it fits any compliant cabinet using the included 20-inch friction slide rails.

How much depth clearance does the 9.84-inch chassis need inside a rack?

The chassis itself is 9.84 inches deep; allow extra space behind it for cables and the 20-inch slide rails to extend fully.

How do I install the PWM cooling fans without vibration noise?

Mount the two 40 x 28 mm NMB fans using the supplied anti-vibration pads and connect them to the motherboard PWM headers for speed control.
