Even if you had 100 of these you are only making 1.7BTC per day non overclock

Just the figures don't add up - PSU - Power cost - Shipping fee's - If you have the money then yeah would be a big risk
I was looking to set up a UK Farm well up in Scotland free cooling aha.
If you ran 100 S1s say in the UK to buy these in inc custom fee based at 500USD per ant = 1.29BTC per ant = 129BTC PSU per ant 0.11 BTC
100 S1 - 129
100 PSU - 11
Switch - 1.35
Racks - 3
Custom power - 2
Total setup BTC cost - 146.35 BTC
£52686.00
$87037.25

Never would you make a profit - get my drift ?
It looks bad and yet you did not really add in the power. You have 350W when it is 100x that.
