I have one of these that I built into a beefy box that was just sitting around. Now it's my dedicated node haha. A little overkill but oh well

I like tinkering with hardware, so yeah use what you got. I just turned a dell into a start9 server. Was a different full node build before. Flashed some thinkpads for varoius projects. Gotta run real gear for real world.
