This would be my first mining rig, and I'm just wondering if all of these parts would run flawlessly, and safe.
MB: Gigabyte GA-970A (with 5 GPU slots)
CPU: AMD FX-4100
HDD: 230GB harddrive (quite old)
GPU: 2x Radeon R9 280X Sapphire Dual-X 3GB OC Edition
3x Radeon R9 280X Sapphire Vapor-X 3GB
Powered Risers: Link to eBay
PSU for the MB: SilverPower 500W (Got this one for free, but I thought that I might need to buy a newer one)
And an homemade DVI-VGA dummy plug
Just recently read that some powered risers could burn, but did i order the "Safe" ones?
