FSP displayed new M Series, S Series, U Series, and W Series chassis at Computex 2026. The lineup covers gaming PCs, compact systems, workstation desktops, and rackmount hardware.
The M581 is a full-size ATX case with a 270-degree curved tempered glass design and support for back-connect motherboards. FSP paired the chassis with temperature-reactive lighting that changes color according to internal temperatures. A display integrated into the rear fan shows real-time fan speed and temperature information.
FSP displayed the M381 alongside it. The case features semi-curved glass panels, support for 360 mm liquid cooling, and preinstalled ARGB fans.
The M221 takes a mesh-focused approach. A tool-free side panel gives builders easier access during upgrades and maintenance.
For compact PC builds, FSP introduced the S350 and S210. The S350 features full-mesh ventilation, support for a 240 mm radiator, and two preinstalled 120 mm fans.
The S210 carries NVIDIA’s SFF-Ready certification and supports graphics cards up to 340 mm long. A carry handle is built into the chassis, while support for 240 mm liquid cooling remains available. FSP demonstrated the case with a complete SFF-Ready build during Computex.
The W Series consists of the W800, W600, and W500. These chassis can operate as rackmount units or tower workstations depending on deployment requirements.
The W800 supports hot-swap drive bays, ATX and CRPS power supplies, and 360 mm radiators. The W600 and W500 offer alternative storage and expansion configurations for professional environments.
FSP displayed three workstation models under the U Series family. The U661 supports E-ATX motherboards, nine PCIe slots, and large 160 mm cooling fans.
The U560 features a dual-chamber layout, support for back-connect motherboards, a magnetic front panel, and black or white color options.
The U500 supports motherboard formats from Mini-ITX to EEB and CEB server-class platforms. Nine expansion slots are available, along with support for graphics cards up to 420 mm long.
A dual-function graphics card holder helps secure heavy graphics cards inside the chassis. The case ships with five PWM fans, including a rear fan with a digital speed display. Support for up to a 480 mm front radiator and a 360 mm top radiator is available.
The U500 supports up to four hard drives and six SSDs. Front-panel connectivity consists of USB Type-C and dual USB 3.0 ports.
FSP has not announced pricing or availability for the new chassis lineup.
