CiT S8i-AC SFF Micro-ATX PC Case 8.3L - Black, TFX

The CiT S8i-AC is a compact 8.3-litre Micro-ATX case designed for home, office and school use. Its small footprint, tool-less assembly and front USB Type-C port make it ideal for space-constrained builds that still need expandable storage and solid cooling.

• Fits any orientation — At just 95mm tall and 321mm wide, it works horizontally or vertically depending on your desk or shelf space. An internal tray with enlarged hole supports taller CPU coolers.
• Front USB Type-C — USB 3.X Type-C port on the front panel alongside USB 3.0, letting you connect modern devices without reaching around the back.
• 80mm fan included — Front-mounted fan with added ventilation holes in the top and side panels to keep a compact system cool without extra purchases.
• Tool-less, quick-release build — Thumbscrews and security screws secure the side panel; no tools needed. Front panel is also secured with screws if desired.
• Holds two 2.5" drives plus one 3.5" — Space for a 3.5" hard drive and up to two 2.5" SSDs (one bay shared between 3.5" and 2.5"), totalling up to three storage devices.

• ✓ Micro-ATX and Mini-ITX motherboards (max 244mm × 244mm)
• ✓ TFX power supplies up to 175mm length (required form factor due to case dimensions)
• Note: AIO liquid coolers are not supported; air cooling only with max 80mm CPU cooler height
• ✗ ATX, E-ATX or larger motherboards do not fit
• ✗ Half-height graphics cards only; max 250mm length

Best for:

• Compact office or school deployments where desk or shelf space is tight
• Small-form-factor builds that need multiple storage drives without bulk
• System integrators seeking Micro-ATX flexibility in an 8.3-litre envelope
• Builds using modest CPU coolers and half-height graphics cards

Trade-offs:

• Large or high-end graphics cards — limited to half-height and 250mm maximum length
• Tower CPU coolers — 80mm height ceiling rules out most air towers and all AIO coolers
• Full-size ATX motherboards — Micro-ATX and Mini-ITX only
• Quiet or enthusiast cooling builds — single 80mm front fan provides basic airflow only, no rear or top exhaust options
• Power users needing four or more drives — maximum three storage devices (one 3.5", two 2.5")
