Re: [3500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool
12GB should be enough, I'm using 16GB merge mining 8 coins & it's a bit overkill tbh. Mining is also how I learned to use Xubuntu - it's an excellent & fun way to do it eh? 
It's a great learning curve.I put Ubuntu Server on it, but I'm struggling with the strict text interface, so I broke down and put ubuntu-desktop on for now - until I am more confident.
I'm just doing install after install of everything from the raid0 setup, bare minimum server install, updates and everything needed for the p2pool server and merge coins.
Get used to it, get comfortable, break it, fix it, break it, fix it, rinse and repeat. I'll be ready to go live with it, perhaps, in a day or so.
Any and all advice welcome.
Cheers.
Check out webmin. Makes managing a text based linux server _so_ much easier.
