Standard spine
A 20mm 280mm radiator with 25mm fans fits at the top and bottom. The side rails take 25mm fans on both sides, or a third 280mm radiator on one side.

Perseus Cases
18L, sandwich layout, up to three 280mm radiators.
The layout keeps the cooling capacity without giving up the flexibility of a small form factor build.
The fascia takes its shape from the columns of the Parthenon. The name is a nod to how the case was made: not by one designer, but by several.
Key features

A 20mm 280mm radiator with 25mm fans fits at the top and bottom. The side rails take 25mm fans on both sides, or a third 280mm radiator on one side.

Rotate the spine and the top slot opens to 63mm. Most 280mm AIOs fit, with intake fans still at the bottom and more room for the GPU above. With the spine in its four-slot position, over 70% of flagship AIB cards fit with an AIO on top.

SFF loops rarely have room for an internal reservoir. The rear panel takes a pair of quick disconnects, letting you fill from an external pump or run the loop to an external radiator.

The fascia lifts off for access. Its plate position can take the PANTHEON logo plate or the front I/O panel once available.
