Got some new hardware
Just picked up a couple of used boxes on local Craigslist for $100 USD total. Both i7-3770 w/8GB RAM. Now I just need to get a couple of decent GPUs. Gladly retired an old P4 and C2D because the electrical system in my old apartment is stressed to the max. After I see how much power draw I need for the GPUs when I get them, I may try to bring the C2D back online.
