In-Win IW-RF100S 1U Short-Depth Chassis 250mm with 265W PSU
The In-Win IW-RF100S is a 1U, 19-inch rackmount chassis that is only 250mm deep. That makes it ideal for building your own pfSense or OPNsense firewall, a small router or a low-power server that has to fit in a shallow wall cabinet alongside switches and patch panels.
It takes a Mini-ITX motherboard (6.7 x 6.7 inches) and comes with a 265W 1U Flex power supply rated 80+ Bronze. Inside there is space for two drives (2x 3.5-inch or 2x 2.5-inch), and cooling is by 40 x 28mm PWM fans: the chassis supports two, up to a maximum of three. The front panel has power and reset switches, two USB 2.0 ports and power, LAN and drive LEDs.
The chassis is made from 1.0mm SGCC steel in black, measures 482.6 x 250 x 44mm (W x D x H) and weighs about 4.2kg. It has no expansion slots, so choose a motherboard with the network ports you need built in.
