Compact 1U rackmount chassis for space-limited

The In Win IW-RF100-S315 is a 1U rackmount server chassis built for environments where rack depth is at a premium. It accepts Mini-ITX and ATX motherboards up to 12" x 10" and includes a single 315W Flex-ATX 80+ Gold power supply. Two NMB 4028 PWM fans with anti-vibration mounts provide cooling, while front-panel LEDs show power, drive and LAN activity. The unit meets the EIA-RS310D standard and ships with a 20" friction slide rail kit.

Verify motherboard size.

Confirm that your motherboard fits the 12" x 10" maximum dimension and that the 315W supply covers the CPU, memory and add-in card you plan to install. The chassis offers one full-height PCI slot via a riser card, so only a single expansion card is possible. Internal drive options are two 2.5" bays or one 2.5" plus one 3.5" bay, with two additional 2.5" bays available as an option. Front I/O provides two USB 3.0 ports, power and reset buttons.

Fits standard 19" racks

At 1.75" high, 19.00" wide and 14.37" deep, the chassis mounts in any standard 19" rack using the included slide rails. The short 14.37" depth leaves valuable clearance behind the rack for cable routing and airflow. Tool-free drive cages speed up drive swaps, and the front-or-rear I/O access choice lets you orient the chassis to suit your aisle layout. The 7.61 lb weight keeps structural loading low.

Questions about this item

What comes inside the IW-RF100-S315 box and what must I buy separately?

The chassis includes a single 315W Flex-ATX 80+ Gold power supply, two NMB 4028 PWM fans with anti-vibration mounts, a 20-inch friction slide rail kit and a full-height PCI riser card; you must supply the motherboard, CPU, memory and storage drives.

The specs list Mini-ITX and ATX motherboard support — which should I choose for this 1U chassis?

Both Mini-ITX (6.7" x 6.7") and ATX (12" x 10") boards fit, but ATX gives you more expansion slots and rear I/O while Mini-ITX leaves extra internal space for airflow in the 1.75" height.

What does the 315W 80+ Gold rating mean once the server is running?

It means the included Flex-ATX supply delivers up to 315W continuous power at a minimum of 80% efficiency at typical loads, reducing heat and electricity cost for the installed components.
