Ant Esports SI15 M-ATX Mini Tower Case

The Ant Esports SI15 is a compact Mini Tower cabinet designed for Micro-ATX and Mini-ITX motherboards, making it an accessible choice for budget-conscious builders who want a small-footprint desktop without sacrificing compatibility. Built from a combination of ABS plastic and SPCC steel, the chassis strikes a practical balance between rigidity and weight, while the metal side panel adds structural integrity and a clean, understated look in matte black. Despite its compact dimensions of 305 × 168 × 352 mm, the SI15 accommodates mainstream discrete graphics cards up to 270 mm in length, giving builders meaningful GPU flexibility within the mini-tower segment. CPU cooler clearance reaches up to 145 mm, which comfortably fits most tower air coolers designed for compact builds. Four expansion slots provide room for a GPU alongside additional peripherals without crowding the interior. Storage options are generously sized for the form factor: two 3.5-inch drive bays and two 2.5-inch bays let you combine traditional hard drives with solid-state drives in the same chassis. Cable management support is built in, helping keep the interior tidy and airflow unobstructed. The front I/O panel is practical and current, featuring one USB 3.0 port, one USB 2.0 port, a combined audio and microphone TRRS jack, an LED activity indicator, and a power button — everything needed for day-to-day use within easy reach. Cooling is handled by a single pre-installed 80 mm rear exhaust fan, with no additional fan mount positions listed for the front, top, bottom, or side panels. The SI15 ships with a one-year manufacturer warranty and is sold in black.
