I want to build a cluster of odroids. I know profitability is really small, but price and power consumption is low too! I still want to try this!

Which odroid gives the best hashrate/watt?
And which one gives the best hashrate/BTC spent?

Yes, profitability is really small, I have heard from friend that it takes more than 2 years to profit. Odroid XU4 is good for mining and average hashrate is 380 H/m. MC1 is better option but it's price is high (checked some months ago). Check these two threads on reddit and on btctalk, hope this will help you:
