All four graphics cards have been custom water-cooled. The original air cooler has been replaced with a full-cover EKWB (EK Water Blocks) water block (Quantum I think) and matching backplate. It is designed for use in a custom liquid-cooling loop.

These were all used in sim racing setups, however have since been upgraded so their owners sold them on.

Each card has been tested with furmark.

2 of these cards have their original boxes, however the other two do not.
