If the heat is generated inside the item then black will radiate the heat best, if the heat is going to be radiated into the item, ie from a hot engine the shiny surface will reflect more heat. Shouldn't be a huge difference between a polished surface and a slightly dulled casting.
Roughness - wonder if the larger surface area helps with radiation?
All quite marginal - the IC and and ice will make this machine quite different to an SRT! (Plus the lack of interior and custome ECU)
