MasterBox 500


When Lightning Strikes

Inspired by sci-fi battle suits, MasterBox 500 features a futuristic geometric facade embellished with ARGB circuit vector designs. The chassis component support has been upgraded to accommodate a wider array of cooling solutions. The top and side panels are easily removable, allowing for greater access and ease during installation, maintenance, and upgrades.


ARGB Front Panel – The iconic MasterBox geometric facade features minimalistic, circuit inspired ARGB strips, giving the chassis a stylish and futuristic profile. The glossy rim of the lower intake shroud increases airflow while catching light illuminated via the ARGB strips and fan, creating a cohesive, iridescent theme. ARGB lighting can be effortlessly managed via a dedicated button on the I/O panel.

FineMesh Front Panel – Cooler Master’s FineMesh technology excels in providing maximum airflow, superior dust filtration, and amplifies the beauty of ARGB SickleFlow PWM fans installed with a scattered glowing effect.

Removable Top Panel – Users may remove the top panel entirely for improved access to components during component and hardware installations.
