Ant Esports SI28 ATX Mid Tower Case

The Ant Esports SI28 is a compact ATX mid-tower PC cabinet designed for budget-conscious builders who need solid functionality without unnecessary frills. Built from a combination of ABS plastic and SPCC steel, the chassis measures 286 mm (L) × 188 mm (W) × 435 mm (H), making it a space-efficient choice for home, office, or entry-level gaming setups. The SI28 supports ATX, Micro-ATX, and Mini-ITX motherboards, offering flexibility across a wide range of mainstream and budget platform configurations. Seven expansion slots give you room to install graphics cards, sound cards, or other PCIe peripherals without compromise. The case accommodates GPU cards up to 270 mm in length and CPU coolers up to 162 mm in height, covering the majority of mid-range air coolers and reference-style GPUs on the market. Storage options include one 3.5-inch HDD bay and two 2.5-inch SSD bays, allowing a mixed storage configuration — a spinning drive for bulk data alongside solid-state drives for the operating system or frequently used applications. Cooling is handled by one pre-installed 120 mm rear exhaust fan. The rear fan position is the only supported fan location on this model; there are no front, top, bottom, or side fan mounts, so the included fan serves as the sole active airflow solution out of the box. The front I/O panel is practical and straightforward, featuring one USB 3.0 port, two USB 2.0 ports, one HD audio combo jack, one LED activity indicator, and a power button — everything needed for day-to-day connectivity right at the front of the case. The cabinet is finished in black and carries a 1-year manufacturer warranty.
