The ACER U300W Micro ATX Business Case in White is a space-efficient chassis built for reliable everyday computing in office and home workstations. Designed to support Micro ATX and ITX motherboards, this compact case helps you create a clean, organized setup without sacrificing core compatibility for essential components. With a durable A-grade SPCC steel body (0.8mm thickness), it offers a sturdy foundation for long-term use—ideal for users who want a practical business PC case that looks professional and stays dependable under regular workloads.
Constructed from A-grade SPCC material with 0.8mm thickness, the U300W is engineered to resist everyday wear while maintaining structural stability. Compared to thinner sheet-metal designs, this kind of steel build generally helps reduce panel flex during installation and upgrades, making it easier to work on your system when adding storage, upgrading cooling, or swapping components. The white exterior also gives a modern, office-friendly appearance that blends well with desks, meeting rooms, and home workspaces.
This case supports Micro ATX and ITX motherboard formats, making it a strong choice for compact business PCs, light professional workstations, and efficient home setups. If you’re building a system for tasks like office productivity, web-based work, and general multitasking, Micro ATX provides a balanced platform with room for expansion while still keeping the overall footprint manageable. For users who prioritize minimal space, ITX compatibility helps keep the build compact and tidy—especially useful in small rooms or shared office environments.
The ACER U300W is designed with versatile cooling support to match different performance needs. It supports multiple fan configurations, including 2x 80mm or 2x 90mm fans at the top, 1x 80mm or 1x 90mm fan at the rear, and 3x 90mm or 2x 120mm fans at the bottom. For users who prefer quieter operation or improved thermal management, the case also supports a 240mm water cooler on the left side panel. This flexibility makes it easier to tune airflow for your CPU and overall system temperatures—an important factor for stable performance during long work sessions.
To support practical upgrade paths, the U300W provides clearances for essential hardware. It supports a maximum CPU cooler height of 135mm, helping you install a wide range of air coolers suitable for business-grade processors. For graphics cards, it supports VGA card lengths up to 310mm, which is helpful when pairing with mid-range GPUs for workstation graphics tasks or smoother visual performance. The PSU form factor is compatible with ATX or Micro ATX power supply units, giving you flexibility when selecting a power supply for your build.
For everyday convenience, the front I/O panel includes two USB 3.0 ports, one USB 2.0 port, a Type-C port, and an HD audio jack. This combination is especially useful in office environments where users frequently connect peripherals such as headsets, external drives, keyboards, and mobile devices. Having Type-C support up front also improves convenience for modern devices, reducing the need to reach behind the desk for connections.
If you’re looking for a compact Micro ATX business case that supports both ITX and Micro ATX motherboards, offers flexible cooling options (including 240mm water cooling), and supports GPUs up to 310mm, the ACER U300W is a practical fit. Its durable A-grade SPCC build, modern front connectivity, and manageable dimensions (350 x 165 x 278 mm) make it well-suited for small office setups, home workstations, and builds where cable management and space efficiency matter. For buyers in Bangladesh, it’s a dependable chassis choice when you want a clean, professional look alongside straightforward component compatibility.
