Description 
The SI25 is a mid‑tower cabinet made by Ant Esports, with support for ATX, Micro‑ATX and Mini‑ITX motherboards. 
The case size is about 350 mm length × 180 mm width × 410 mm height. 
Build material includes a solid steel side panel, giving it a sturdier, simpler look (no tempered glass on that side). 
For cooling, it comes with capacity/support for up to three 120 mm fans in the front and one 120 mm fan at the rear. It often ships/pre‑installed with one 120 mm fan at the rear. 
Liquid cooling support includes up to a 240 mm radiator at the front, and a 120 mm radiator at the rear. 
GPU clearance (max supported video card length) is up to 315 mm. 
CPU cooler height clearance is up to 157 mm. 
Storage options are generous: supports both 3.5‑inch HDDs and 2.5‑inch SSDs. Number of bays is roughly 5 HDD slots or combinations like “5 × 3.5″ or 4 × 2.5″” depending on which slots you use. 
There is a 5.25‑inch optical drive bay, which many newer cases omit, so that’s a feature if you need one. 
Expansion slots (for PCI / GPU etc.) are 6 in number. 
Front I/O includes USB ports, audio/mic, Power & Reset buttons. To be specific: 2 × USB (types not always clearly USB3), audio in, mic in, power button, reset button. 
Design is basic and functional: mesh or perforated front for airflow, no fan slots on top, no bottom fan/vent slots in most spec listings.
