Rosewill Micro ATX Mini Tower Desktop Computer Case | Pre-Installed 400W Power Supply | 1 x 120mm PWM Fan | 240mm & 280mm AIO Support | 2 x USB 2.0 | 2 x USB 3.0 | Gaming & Office PC - FBM-X5

The Rosewill FBM-X5-400 is a high-utility solution for budget office builds and entry-level gaming PCs where minimizing cost is the priority. Its standout feature is the pre-installed 400W power supply, which provides an immediate, "out-of-the-box" foundation for low-power systems. Builders frequently praise the inclusion of dual USB 3.0 and USB 2.0 ports on the front I/O, as well as the surprising compatibility for up to a 240mm radiator, offering cooling flexibility rarely found in the ultra-budget Micro-ATX category.

The primary trade-offs include thin steel construction and limited clearance for cable management, which can make tidy builds challenging. Additionally, the non-modular, 400W PSU is strictly for light-duty setups and won't support high-end GPUs. However, when contextualized against its aggressive price point, these flaws are easy to overlook. For a streamlined workstation or a simple home server, the FBM-X5-400 is an essential "buy" that delivers a functional chassis and power source for less than the cost of most standalone mid-range cases.
