About This Product
The Sigma ORCA-B is an ATX mid-tower case designed for budget-conscious builders. Its feature set, including USB 2.0 front I/O and limited fan support, indicates suitability for basic office or entry-level gaming systems. Compared to modern cases, it lacks contemporary features like USB 3.0 or tempered glass, positioning it for users prioritizing cost over aesthetics or advanced connectivity.
