The Professional Standard: CiT SI001BK Micro-ATX Case
In the modern workspace, efficiency isn’t just about software; it’s about the physical space your hardware occupies. The CiT SI001BK Micro-ATX Case is a refined solution for system integrators and DIY builders who demand a professional aesthetic in a compact “slim desktop” or “micro tower” orientation. At just 15 liters in volume, this chassis manages to pack in full Micro-ATX motherboard support while maintaining a profile thin enough to disappear into a workstation setup or a home entertainment unit.
At Overclock.uk, we recognize that business builds require reliability and ease of maintenance. The CiT SI001BK Micro-ATX Case delivers on both fronts with a high-quality 0.8mm SGCC steel frame that provides significantly more structural integrity than standard budget cases. Whether positioned vertically using the included stands or tucked horizontally under a monitor, this chassis is built to last.
Modern Connectivity with USB-C
One of the standout features that elevates the CiT SI001BK Micro-ATX Case above other slim enclosures is its modern I/O array. While many budget compact cases stick to older standards, this model features a front-mounted USB 3.1 Type-C port. This allows for lightning-fast 10Gbps data transfers and easy connectivity for modern mobile devices and external NVMe storage.
In addition to the Type-C port, the front panel includes:
-
2 x USB 3.0 Ports: For high-speed peripherals and thumb drives.
-
2 x USB 2.0 Ports: Perfect for keyboards, mice, and legacy devices.
-
HD Audio & Mic Jacks: Seamless connection for office headsets and conferencing.
Toolless Design and Easy Assembly
Building in a small form factor case can often be a frustrating experience, but the CiT SI001BK Micro-ATX Case simplifies the process with a thoughtfully engineered toolless design. The internal drive cages and side panels are designed for quick access, allowing system integrators to swap components or perform upgrades with minimal fuss.
Despite its slim 145mm width, the interior is surprisingly spacious. It supports a Slimline Optical Drive, making it an excellent choice for businesses that still rely on physical media or for users building a dedicated home-theatre PC (HTPC). For a deeper look at the installation process and component compatibility, you can view the official technical overview at CiT’s resource page.
Thermal Management and Airflow
Small cases are often prone to heat buildup, but the CiT SI001BK Micro-ATX Case utilizes a “U-type” right-hand side panel and a TAC2.0 thermal airflow channel. This design ensures that the CPU and motherboard components receive a steady stream of fresh air from the side intake. To further enhance cooling, the rear of the case supports a dedicated 80mm exhaust fan, which helps pull warm air away from the processor and out of the chassis.
For those planning a 2026 build with higher-performance internals, we recommend pairing this case with low-profile air coolers (up to 115mm in height) to maximize the “chimney” effect of the vertical airflow. You can find detailed thermal testing results on various community forums or by consulting the KitGuru guide to SFF thermal optimization.
Power Supply and Compatibility
To maintain its slim profile, the CiT SI001BK Micro-ATX Case is designed to house a TFX Power Supply. This specific form factor is standard for slim desktop cases, allowing the chassis to remain thin while still providing enough wattage for modern multi-core office PCs.
