Ready-to-build ITX chassis

The NCORE 100 MAX is a 15.7-litre Mini-ITX tower that arrives with a custom 120 mm AIO liquid cooler and an 850 W SFX Gold ATX 3.0 power supply already installed. Pre-routed cables and an anodised aluminium side panel keep the internal layout clean for first-time builders and experienced enthusiasts alike. A single 120 mm SickleFlow PWM fan handles exhaust airflow at up to 1800 RPM.

Expandable width absorbs sustained GPU heat

Under continuous load the case can widen from 155 mm to 172 mm, creating extra clearance for graphics cards up to 357 mm long, 79 mm thick and 180 mm tall in the expanded configuration. The front-mounted 120 mm radiator dissipates CPU heat directly to fresh air, while dust filters on both side panels maintain airflow over long sessions. CPU cooler height remains limited to 48 mm, so the included AIO is the intended thermal solution.

Replaces a DIY SFF kit, PSU, riser and AIO purchase

Builders who would otherwise source a separate SFX power supply, PCIe 4.0 riser cable and 120 mm liquid cooler can consolidate those components into one validated package. The integrated 850 W unit uses custom-length cables that eliminate slack, and the riser is sized for the chassis to guarantee signal integrity. The jump is worth it when a compact 3.9-slot GPU and Mini-ITX motherboard must coexist without cable routing compromises.

Questions about this item

Will a 3.5-slot graphics card fit without removing the side panel?

The case expands from 155mm to 172mm wide, allowing cards up to 357mm long, 79mm thick and 180mm tall including the power connector.

Can I use a standard tower CPU cooler with this case?

Maximum CPU cooler height is 48mm, so only low-profile coolers or the included 120mm AIO will fit.

Does the included power supply support ATX 3.0 and PCIe 5.0 graphics cards?

The pre-installed 850W SFX Gold unit is ATX 3.0 compliant and ships with custom-length cables for the internal PCIe 4.0 riser.
