You could get a 6pack of antminers s5 for that price but you should really think about it.
How much are you paying for electricity? Is your internet and power reliable? What are the temperatures in summer?
You really need great conditions to profit from home mining these days.
An S5 does have a power draw of 590W, since you need a PSU, network, lighting,... Let's round it up to 600W.
5*600 = 3Kw.
I'm not an electrician, but i suppose most domestic circuits won't have a problem with this extra power draw.
Do realise you're creating 3Kw worth of heat. Also, there will be noise.
As for the profits:
5 * 1155 Gh = 5775 Gh.
At current diff, BTC price and block reward:

Personally, in order to be interesting to mine with S5's and free power, you'd need to be able to buy 20 S5's + 20 PSU's + racks + network + cooling for that $2000. This might pose a challenge, since you'd only be spending $100 per S5+PSU+1/20 of a rack + 1/20 of an AC + shipping + customs charges + ...
In this case, you'd have 20*600W power draw = 12Kw, i'd suggest to contact an electrician!!! Also, do realise there is no thing like "free electricity". Sure, sometimes you rent student housing, or your employer doesn't mind if you install a miner in his server room, but 12Kw of power draw might draw attention to your mining activities... Free electricity might lead to an eviction or getting you fired, so think twice before doing this...
20*1155Gh = 23100Gh

I'd strongly suggest to buy a second hand S7, S9, Avalon 6, Avalon 721 or Avalon 741 instead of an S5 and re-do the complete calculation BEFORE buying anything.
