Nothing. It’s just fun.

But then it would have been lame. Who cares? If your old machine is a x86 less than 10 years old it’s most likely faster than the Pi. But that’s not the point. The point is to pair a cheap fun computer with a humongous and expensive card and see if it works. Because it’s fun.

personally I was interested in the capabilities of the pci-e bus as I abuse it in every other computer I can get my hands on (the rpi4 really did not like that treatment).

to your point about 'meaningful' though, indeed the ole College Try to run Crysis on a Samsung NC-10 would be far more glorious! But I assure you this was very fun for me.

Idk you can buy a new Pi for cheap and they're all the same, old machines vary and are not always available. I'm certainly not going to do it but it's not uninteresting imo
