Zalman P40 DS ATX Mid-Tower Case

The Zalman P40 DS is a black ATX mid-tower case built around a 9.1 inch LCD panel mounted on the bottom panel. It supports ATX, Micro ATX and Mini-ITX motherboards and comes with four 120 mm PWM ARGB fans pre-installed. The chassis offers seven expansion slots and a tempered-glass side window for component visibility.

Build quality, connectors and daily use

A bottom-mounted power-supply bay keeps cables tidy, while dust filters on the intake areas simplify maintenance. The front I/O cluster provides USB 3.0, USB Type-C and audio jacks for quick peripheral access. With room for up to ten fans in total and support for a 360 mm radiator, the layout accommodates both air and liquid cooling configurations.

Practical limits of the standard and interface

Graphics cards up to 420 mm long and CPU coolers up to 165 mm tall fit without modification. The power-supply cavity accepts units up to 180 mm deep. Builders who need more than seven expansion slots or a larger radiator than 360 mm will need a different chassis.
