If you just want a 6 GPU rig the Biostar TB85 mining motherboard is a good and less expensive option. I have run up to 7 cards using a PCI-E expander card.

BIOSTAR TB85 LGA 1150 Intel B85 SATA 6Gb/s USB 3.0 ATX Motherboards - Intel - $74.99

RX 570 4 GB $250> can easily get 28+ MH/s ETH + 700 MH/s DCR dual mining after a Bios mod. ROI is ~127 days and about 103 days if you dual mine without power costs.

Keep in mind the price you sell at will affect your ROI more than anything.

with free electricity you should be good  , the question is,  is your ROI .

Dont forget about a few very important things :
None of those calculators you are seeing on the web can tell you what's coming tomorrow , months later or 6 months later !
Those calculators telling you about today , at that moment when you typing in your information !
No one can tell you how much profit you going to be able to make !
No one can tell you it's going to be profitable for you or not !
No one can tell you for sure what's going to happen with cryptocurrency ,
....price might going down or up ,
....difficulty is going up as more and more ppl get into mining ,its mean you going to mine less and less coins ...
