A few questions as a Miner who got in via Scrypt mining since I was told BitCoin wasn't profitable anymore but doing my own calculations, seeing that this was sort of a lie (Or at the very least, Spondoolies made it profitable again.) Excuse my ignorance if these questions have already been answered but I was trying to search through all 100+ pages of this post and didn't find any answers as of yet.
I've already seen Spondoolies on CCN's website and people have already been posting reviews on this ASIC, so I'm assuming this ASIC company is already established and trust worthy manufacturer unlike the millions of ASIC companies popping up on Scrypt sites talking about how there taking pre-orders but still months away from launch.
How long does it take to order an SP-10 Dawson from them (Does it have to ship from Isreal or do they have a local shipping site?)
I've read that the SP-10 produces 45 db of noise yet some people are complaining this is too loud... Are they just hyper-sensitive of hearing or do they not have basements/living rooms to store these ASIC's? And are there any methods of lowering the noise levels if indeed they are louder then 45 db? (I live in NYC so 45 is REALLY quiet even for night time here)

I've also read that the units get really hot underneath, and I was interested in getting racks for multiple units, but how do the units not burn each other (Or at the very least cause overheating) if there stacked on top of one another?
Any information or help at all would be greatly appreciated as someone who's been taught since entering ASIC mining to ignore SHA-256 and focus purely on Scrypt.

Well about the noise, installed two sp10's in a datacenter yesterday. Today i got a phonecall from the datacenter.
It is a big datacenter (+1000 racks), they told me the sp10's are the loudest machines they ever had in the building....
