I got the zipties, but I'm not exactly good at it. Plus I don't really plan to show this off anymore.
The GPU is currently a MSI 6670 2GB GDDR3 that runs on PCI-E x16 and doesn't need a secondary power connection. I plan to buy a R7 270X or equiv. when I can. But for now the 6670 works great at 1440x900 and 1860x1050.
