I suspect the actual PC used is at least fairly powerful though. Like someone else said it's likely using ECC as its mission critial, so chances are it also has other expensive server parts inside. Not all powerful computers actually look like anything fancy at all. This post reminds me of things like the watercooling subreddit and the amount of effort and money they put into things like aesthetics, that don't actually improve performance at all. Even though the original point of watercooling was performance.
