I wouldn't build any new rigs just ethereum mining.
Existing rigs repurposed would be fine (Hi Phil).
If you're building a rig for something else (like I did this past week) running it as an ethereum miner for a while to defray PART of the cost is a usefull thought.
The way the price keeps drifting down and the diff keeps climbing makes achieving ROI on a new-built rig look pretty iffy at this point.

Also the Ehtereum will become PoS early next year. The huge amount of GPU will have to find anther coin to mine.
I think the excessive amount of mining hardware will crash the second hand graphics card market.
you can pretty much bet on that .cards that were going for 50-75 bucks used (if you can find them) now go for 225 plus
ethereum should have made this setup with sha-256 equip..the hype/cheer-leading of all these old miners back on a network again would have been epic.....the price
would have been higher imho..and as far as difficulty who cares..gonna be a pos coin anyway
just saying... a hell of a lot more asics sitting around (my knc 550gh Jupiter now acting on the bottom self as a gravity assist device to keep my Titan Miner bench rooted
to the Earth)
A lot of us out there just can't sell.......... 'my precious' that made me 53 BTC ..I mean really for what on Ebay 100 bucks I could get for it .....it would be like selling the family cat
but yeah ..truth be told they probably could say they were going in 1 month to pos coin....would only hurt the miners probably would help the price in that the market
would see them as 'ahead of their timeline plan' lol
