This is an almost entirely white build inside of the Cooler Master H500P Mesh.
Certain parts have been painted to better fit the theme. Most notably the vertical GPU bracket which comes in black, but also all PCIe slot covers and the metallic piece which holds the radiator in place at the top of the case, for the lack of a better word.

Not mentioned in the parts list is:
A set of CableMod extension cables;
A Phanteks 220mm riser cable (with chopped off latch to fit the vertical bracket).
