"Hey fellow miners and tech enthusiasts, I'm excited to kick off this thread where we can share our experiences building our dream crypto mining rigs from scratch. I've been messing around with crypto mining for a while now, and I've learned that it's not just about throwing together some GPUs and expecting to rake in the coins - careful planning and execution are key. What kind of setup are you guys working with, and what's the most challenging part of building your rig?"
