Best and easiest solution, don't jump into mining without a bit of knowledge. I would personally buy a cheap older miner to get used to it, maybe an s3 and put the rest DIRECTLY into btc.

You should check how mining work first. Investing in a big device like that for the first miner is a really bad idea.
Over that, KNC seems to have a lot of problem with fire.
I will suggest , S5 from bitmain, SP20 from spondoolie or Avalon 4.1 from Ehash.com
These are better watt/gh miner and you will earn more with them.
Also, you should maybe wait since the ext gen should arrive soon (hope so)
You could also look for a SP31 or SP35 from spondoolie if you have 240V
