So basically he's buying this stuff to show off. Because I really doubt he has anything productive to do, or indeed even knows how to utilize, 24 cores.
So do we know what he does as a day job? His twitter has words like "computer scientist" and "roboticist" in it, but I find it unlikely that he's got legitimate employment in a profession like that and runs this insanely profitable animal dildo business on the side.
Sorry, but everything about this guy is seedy. He's gotta be involved in drugs or something like that, I just don't see that kind of money adding up otherwise. Conspicuous consumption is one thing; nine thousand dollars on hard drives and three-dozen-core computers take that to a whole new level.
I know there's "money" in adult toys and porn and stuff, if you do it right- mostly because of price gouging- but not THAT kind of money.
Edit: Flipping through his Twitter, it looks like he's running e621 on the 24-core box. Maybe more; but at some point you become I/O-bound, and unless I'm wildly wrong about current technology- it happens well before you fully utilize 24 CPUs.
Really you can only use that kind of parallelism on some kinds of scientific computing. You sure can't justify it as a fucking web/database server.
I also see at least once he mentions that people are still complaining about the lack of response to e621 takedown notices. I seem to remember the prediction here was that he'd change that, since his business, such as it is, relies on good relations with artists.
