Hey Mate,
I'm a newbie as well and have been looking at Avalon 6s actually really favorably to the s7 as a home hobby miner.
if you are looking at 10 i would contact blocc.co directly they are the world wide distributor and have probably supplied zoomhash. Reason being that they sell a 10 pack at a much cheaper rate -
http://www.blockc.co/collections/bitcoin-miners-shop-avalon-blockc-co/products/avalon6-bitcoin-miner 10 for 13,900 and they will throw in the RPi controller for free (zoomhash charge $75 i think)
You will only need one RPi controller for all 10 A6's
You will need PSUs for all your rigs which could be expensive - BlocC has PSUs they can sell you just ask the sales staff (the rate imo is good!) BUT I would wait for the guys on this thread to test the undervolted PSUs if you are considering running these ever at a lower hashrate but higher effency -
https://bitcointalk.org/index.php?topic=1257327.0I'm waiting on these guys atm! They seem like good people who know their shit and have taught me a bunch in the last couple weeks.
For pools I would go with Kano's pool
https://bitcointalk.org/index.php?topic=789369.0 Pools is a massive debate in itself but read this topic to get an idea of the 'behind the scenes' dealings between pools and the debate about what's good for the BTC network -
https://bitcointalk.org/index.php?topic=1085800.0 This topic convinced me to never mine on Eligius or the bigger PPS pools like Antpool and Discus Fish (And I feel dirty for giving them my hash now)
But if you are just after the BTC and making ROI asap you may have different priorities in choosing a pool.
BTC mining from my knowledge doesn't really require a fast internet connection but a reliable one so you should be sweet!
hope this helps! super jealous of your 10 units!
