In terms of cool, the XSPC Photon Tube Reservoir is all that and more. The decision to lose the plastic in favour of glass was a huge boost in my eyes. While many may scoff at this, put a plastic cup next to a nice clear drinking glass and look at the difference. Glass has a much richer, reflective appearance and appears to be a much higher quality. This is exactly the same effect we see in the Photon, and pictures just don’t do it justice. It looks positively remarkable in person.
