Try zapstream as vanity npub.  With 80 cores that should be possible. An 8 character vanity (240 pow) took me only a bit over 5 days using 4 cores. 

 I'm a bit of a miner myself.

 Oh it's in your house, no, that's a bad idea. Mine is in a data center, power included in the contract so don't care 😆  

 Yes this server will be soon too, i just got it today, its setup day, then i need to put in data center
