Yeah i was wanting to begin kinda slow as low funds. Also thought someone on here could have something they just wanted to sell too. THanks for your help. I thought the fans would be kinda loud or others say they are. So the s5's have built in controllers do the s7's too? Some of them look good but then don't come with power supply to so that's another hundred and puts everything in a different cost perspective of i could get something better for same money with one. 
S5 and s7 have there owner controller. Don't think you have to buy a expensive power supply. All my power supply's are like 10 to 20 bucks bucks off amazon. Just 1000 watt server PSU. or 1200 watt server PSU.
The fans on the s7 and s5 are kinda loud but I have mine turned down to around 25% on the s7 and 35% on the s5's. I also don't max out the miners ether so they last longer. My s7's are running around 3.7 ths and s5's around 900 ghs to 1.2ths. Temps on the s5's are lower 50's during the day below at night and s7's hover around mid 60's.
