This was a trend in PC building back in the early-mid 2010s but seems to have lost momentum around 2017/2018

From what I recall, it stopped being a fad because outside of the cool factor, it was found to be horribly inefficient (cost/performance) at actually cooling the computer compared to air or water cooling.

Reminds me of the opening rift to Pink Floyd’s Wish You Were Here, based off your recording. Doesn’t quite feature the grunginess you mention.
