This category contains PC cases supplied with a power supply already fitted, mainly mid tower desktop cases, plus some server-style chassis. It suits people building an office PC, a home system or a workstation who want the case and PSU in one purchase. Brands in our range include LC-Power, Cooler Master, Supermicro and Zalman.
How to choose a case with a power supply
Power supply wattage. Add up what the processor and graphics card draw, then leave some headroom. A basic office build with integrated graphics needs far less than a gaming PC with a dedicated graphics card. Bundled units are usually sized for modest builds, so check the wattage before you plan a large upgrade.
Case size and motherboard support. Mid tower cases typically take ATX, micro ATX and Mini-ITX boards. Look at the maximum graphics card length and CPU cooler height in the specifications, because these limits decide whether your parts physically fit. Server chassis can be built around specific boards, so match the board before ordering.
Cooling and airflow. A vented or mesh front panel, several fan mounts and pre-installed fans keep temperatures down in a system that runs for long hours. If you want liquid cooling, check which radiator sizes the case supports.
Front connections and drive bays. Front USB 3.0 ports save reaching behind the desk, and a front USB-C port is useful for newer devices. Count the 3.5 inch and 2.5 inch bays if you plan to fit several hard drives or SSDs.
Power supply connectors and efficiency. Check that the unit has the PCIe power connectors your graphics card needs and enough SATA connectors for your drives. An 80 Plus efficiency rating, where listed, means less energy is wasted as heat.

Frequently asked questions
Is a PC case with a power supply included worth buying?
Yes, for office, home and general-purpose builds where the included power supply has enough wattage for your parts. You get the case and PSU together and avoid matching them yourself. If you plan to fit a powerful graphics card, check the wattage first or budget for a separate power supply.
How many watts do I need in a PC power supply?
It depends on your components. A basic office PC with integrated graphics often runs comfortably on a few hundred watts, while a system with a mid-range dedicated graphics card commonly calls for 500 W or more. Check the power recommendation of your graphics card and add headroom for future upgrades.
Can I replace the power supply that comes with the case?
In most standard ATX cases, yes. Any ATX power supply of a compatible size can be fitted, so you can upgrade later if you add more demanding parts. Server chassis with specific or redundant power modules may need matching replacement units, so check the specifications before swapping.
What size motherboard fits a mid tower case?
Most mid tower cases accept ATX, micro ATX and Mini-ITX motherboards. Some larger or specialist boards may not fit, so confirm the supported form factors in the case specifications. Also check clearance for the graphics card and CPU cooler.
