The Wraith 2.0 Elite is an additional distro plate for the Singularity Computers Wraith 2.0 Showcase. A total of two Elite kits can be installed in the front and the top.

The integrated spacers offer enough clearance to supply the radiators with fresh air.

When mounted at the front of the case, the connections for the water cooling loop are positioned at the top, while if mounted on the top, the ports are oriented at the back. The two connections are made in G1/4 inch (BSPP standard) and can be used as inlet and outlet. The function (In/Out) is freely selectable, allowing for optimal orientation for the custom loop. Since the Wraith 2.0 Elite widens the case without reducing the interior space, it is still possible to install two 360 mm large and 60 mm high radiators.
