I just built a mining rig about a month ago, ordering that same exact bundle from gpuShack.
It was great!
I received a MSI 970 Gaming Motherboard, 2x 4GB RAM, AMD Athlon II x2 250 Processor, and a 32GB SSD with EthOS installed on it.
It's a really clean and great OS to get down to mining, and view remotely.
Since it's a less used OS, troubleshooting can be a little bit more tricky, but they do have a support chat that I am often in enjoying conversation with the EthOS community.
