If you were into PC building back in the mid-2000s, you probably remember when Zalman was pushing the absolute limits of hardware design, including with their flagship fanless PC case, the TNN 500AF. It was essentially a 30+ kilogram chunk of aluminum sitting on caster wheels. Nothing subtle about it, just raw, industrial brute force. Fast forward two decades, and these behemoths haven't completely disappeared into history. Every now and then, one quietly pops up on eBay. Or in Denmark, like this one listed for $300.
