Uncertain if i've already done this for the new "used" build but here she goes.
Case: Ultra uncertain of model - cheap like $25
Board: AsRock P55 Pro
CPU: Xeon x3460
Memory: Corsair 8gb DDR3 1866
PSU: Corsair cx750 modular
GPU: Powercolor Radon 7850 2gb
OS: Ubuntu 16.04 LTS -- recently upgraded from 15.10 ruined my experience as no more steam gaming
This one is a full stand alone not a VM, been using it for remote access to my VM's while i work from home. It runs well even on such antiquated hardware the true power of a GNU OS and optimized kernels.
Getting into a lil bit of more advanced shell scripting and mysql db admin with this one.
Not really new to linux or the shell as most of my VM server cluster is ubuntu server(s) running 14.04lts-15.10. I do have a few Fedora servers for testing and learning RHEL.
Currently managing my own teamspeak, postfix server, courier imap, mysql db, zentyal gateway, openvpn and a few other projects.
Wish me luck.
Anyway here's the rig.
