a low quality mercury thermometer costs about £10, and they contain only about 1 cubic centimetre of mercury or less, and guessing how much the pipes on this cooler will contain, this is probably going to cost at least £100, maybe double or triple that (galinstan may be more expensive or cheaper than mercury, but I'm assuming there isnt much difference). I think that its going to be contending with mid to high end water cooling in both price and performance.
