MasterBox 5: You Decide the Inside

Unlock your build’s inner potential with the MasterBox 5: This case’s straightforward design comes with convenientlyplaced cut-outs, making component installation, interior expansion, and multiple interior layouts simple and easy. The MasterBox 5 can also support larger, high-end components, air and DIY water cooling. Keep your system looking clean with the possibility of using numerous routing holes and covers for your PSU.

Exploring the Interior
