Bitmain doesn't do volume pricing, so there's not much money to save in a group buy. You can actually contact GND/cryptoboreas directly if you want to host a few units, they will definitely beat lee's service.
Also, I forgot to lock this thread. Locked!

Possibility of a group buy with the same set up at GND, but with either batch 8, or 9 of the S7? I am interested in lee's group buy, but the .10$/kWh is not near as good as what it seems Great North Data can offer.

If I was to make a comment, it would be that group buys need to deal directly with the manufacturer, NOT the distributor.
Manufacturer is much more flexible (within reason) as they know their bottom line.
Distributor is limited by the MSRP and needs to go back and forth.
At least this is how I see it and that's how it worked with a large and successful SP30 group buy.
I agree with that, but when I directly contacted Avalon they didn't want to directly deal with me--they told me to contact BlockC instead.Manufacturer is much more flexible (within reason) as they know their bottom line.
Distributor is limited by the MSRP and needs to go back and forth.
At least this is how I see it and that's how it worked with a large and successful SP30 group buy.
As for bitmain, their volume pricing is laughable. 100 units will give us a 0.5% discount.
I guess we'll have to wait until prices come down further.

GB in S7 at below listed price is impossible with miners quoted at $2200 (B6)-$3200 (B1, 3,5) on ebay.

the price is to way to high hence the lack of interest. Plus, I think more people wanted the avalon 6 as a home miner to mess with settings (underclock/undervolt..etc) and such not necessarily to be hosted for 3 months than try to ship home. A group buy of the S7 might be better.

Well then, the deadline's come and gone and we didn't get enough interest. Too bad, I was looking forward to picking up a few Avalon6 units for myself! Perhaps we can try again with a later batch.
Those who reserved units please PM me with the address you would like your deposits refunded to.

It's a pity.
Hosting fees are really good and even PSU lease is an idea which should be tested, but units are way overpriced, much more so with BTC at current level.
At 450 USD per BTC it would have been very different (well, if Avalon does not increase their price at 2000 USD each).

Sorry to say...I'm out....a bit to close to call...and if I had no miners at all I'd probably do this just for the 'gamble' and to play with an Avalon6 toy..but got 2 KNC Titan scrypt miners that likely will make more in LTC then in elec all the way thru 2016... so I'm gonna pass on this
anyway good luck...(officially in 'lurk' mode now)

Hey, no hard feelings.
6 to go before we hit MOQ!

Is possible to pay the miner (Blockc.co) by wire or credit card? I can pay all other costs in btc, btw...
I'm not sure, I've send blockc an email.
A wire works, but they don't accept credit cards.
As a general comment: We've got just under 24 hours until we hit the deadline for reservations. If we don't hit the MOQ, we don't hit the MOQ, but if you are interested I suggest you make up your mind sooner rather than later!

ps: the calculation posted brings up something important: the PSU lease. By assuming $10/month for the lease, after 8 months the [half-]PSU is completely paid for. does it become property of the leasee, or do the monthly lease fees become monthly rental fees? Either way, that adds about $60-80 to the above calculations ROI.
The lease is exactly that, a rental over a pre-determined period of time. The initial price I have set for the 3-month contract is to take into account the cost of shipping the PSU's to the DC, any potential failures/down-time (with their return shipping), and having to return PSU's back to me if anyone/everyone decides to end their contract after the initial period. If anyone intends to re-new at that point for another 3 month or longer contract, we can re-negotiate (in advance of the renewal date) a more favourable lease rate given shipping won't be required again.
I can't say for certain how much cheaper the renewal rate will be until I get an idea of failures and/or downtime, but it will absolutely not be going up. I am not looking at gouging anyone here, only trying to provide a more feasible solution to the ownership dilemma, while still covering my bases in case of short contracts/failures, since every failed PSU will need the unit returned to me and a new one shipped out to the DC as quickly as possible (while keeping extras on hand on top of that).
Another issue that could arise if the GB were to strictly purchase the PSU's, who would be responsible for replacing a failed unit outside of the initial purchase? Those members whose serial numbers are tied to it? It's these types of problems I'm trying to help avoid. Also, if you factor in having to sell off all the used PSU packages at the end of different hosting periods in order to distribute the assets fairly to those who are pulling out, you will take a substantial hit on the re-sale value, and have to pay shipping to somewhere in NA. This seems to me to be a reasonably priced alternative to any of that.
In regards to a yearly/unlimited plan, that would be nice but I don't think anyone would be willing to get into a contract (and if they do, to keep that contract) longer than their hosting commitment for pretty obvious reasons. I am fully willing to negotiate cheaper lease rates if anyone signs longer contracts with GND, but to my knowledge for the scope of this GB, only 3 month commitments are initially available.

If you guys have python installed on your computer you can run this python script I wrote. It takes the halving into account, accounts for faster blocktimes when the difficulty increases faster, and allows difficulty increases to change over time. Please don't trust random code on the internet! There's nothing malicious here, but you don't know that unless you can read it (so don't run it if you don't know what you're doing). Source is here:
Of course, if you want a better simulator it'll need to factor in the decline in hosting/PSU costs and the inevitable decrease of difficulty that will happen after the halving. However, I think my calculator is probably the most accurate one out there (its just not very easy to use).
It might be interesting coming up with software that calculates the difficulty based on a distribution of hardware by maintenance cost, factoring in how new hardware coming into the market forces old hardware off.
Finksy doesn't want to promise a specific rate after three months, and I don't blame him at all for that. He wants to see the board/PSU failure rates before he requotes (remember, he's promised to cover failures out of his own pocket). The one thing he has guaranteed is that rates won't go up. I know it's frustrating, but we will have to wait and see on that front.

Of course, if you want a better simulator it'll need to factor in the decline in hosting/PSU costs and the inevitable decrease of difficulty that will happen after the halving. However, I think my calculator is probably the most accurate one out there (its just not very easy to use).
It might be interesting coming up with software that calculates the difficulty based on a distribution of hardware by maintenance cost, factoring in how new hardware coming into the market forces old hardware off.
Very interested, but I think we definitely need to have a clearer picture about the fees after 3 months and also the PSU lease situation as mentioned by klondike_bar. How about a yearly plan or an unlimited plan ending when the miner is no longer profitable?
Great North Data isn't setting firm dates on when their hosting rates are going down.Finksy doesn't want to promise a specific rate after three months, and I don't blame him at all for that. He wants to see the board/PSU failure rates before he requotes (remember, he's promised to cover failures out of his own pocket). The one thing he has guaranteed is that rates won't go up. I know it's frustrating, but we will have to wait and see on that front.

This i my ROI point of view:
This calculation is based on the fact that you have the money to pay for the miner package + hosting for a year, on hand, so that the alternative is to buy coins instead of mining gear for that amount of money.
Calc inputs:
Difficulty increment: 4% #I seriously doubt it will be below 4% on average.
Pool fee: 2.5% #Based on Ant PPS. Even if you are mining on 0% fee PPLNS. You can't expect more than 98% luck on average IMO.
Hashrate: 3500 #Based on 3650TH/s -4%. They have stated +/- 5%, lets try to be realistic.
Hardware price: 1436$ (Ex. hosting/PSU rental)
Hardware price in BTC: 4.373
Watts: 1000
Start date: 11-30
Maintain cost/month: ~58$ #Based on 0.0661$/KWH aka hosting, and 10$/month PSU rental
url snipped
Seems like you will never earn back the amount of BTC you put into this.
Miner cost + 1 year hosting = 1436 + 696 = 2132$ total invested.
If you buy coins today for that amount of money, this will give you 6.41 BTC.
If you buy gear, you pay 4.37 BTC up front, which you won't mine back. Unless you get cheaper hosting or $/KWH.
PS: There are 3 months of hosting at 0.047$/KW, that is not considered in this calc.
PS: Calc does not take halving into consideration. If you can't ROI without halving, you probably can't with it either
Am I missing something?
Better to buy coins than gear, in terms of ROI?
Disclaimer: You can ofc ROI this in terms of $, if BTC price skyrocket. My point being, it's always better to buy coins.

you are not putting btc into it, but $$. Don't put in bitcoin that you already have.
these calculations never account for btc price change, and therefore cannot be trusted.
Start with $$, end up with $$ and put in various bitcoin price scenarios.
Besides, where in your calculations is the RESIDUAL value for the miner?
It was ~55% in BTC and 35% in $$ for SP30 after 12 mo and 53% of SP20 in $$ and astonishing 78% in btc after 10.5 mo (even with a high price paid for SP20 before discount to $400-500).
Thats if you want to diversify your money/risk, but if one or the other its entirely up to what you think the bitcoin price will do.
ps: the calculation posted brings up something important: the PSU lease. By assuming $10/month for the lease, after 8 months the [half-]PSU is completely paid for. does it become property of the leasee, or do the monthly lease fees become monthly rental fees? Either way, that adds about $60-80 to the above calculations ROI.
