I just see one ethernet plug at the bottom of the miner...so no possibilities to enter 4 cords into each unit.

Also agree Giant doesn't make sense at that price. As x11 is not so influenced by elec. price. Giants lower power for MHash doesn't make up for bigger price.  2 Quads are much better than one giant.

What is the timeframe / payment method for the Giant Special?  I am interested in 2-4 shipped to Canada.

So it would be $300 plus an additional 10% off?  Do I order directly from their site and just include your group buy code?

I just got my Baikal Quadruple Miner which I ordered from one of the group buys mentioned in this thread. I just would like to share some experience I've made so far with the miner and with baikalminer.com. I had 2 scrypt miners from Innosilicon and thought I could buy an A4. But then I read the issues they had with multipools and in addition the skyrocketing diff change from Litecoin made me think not to invest in scrypt anymore…at least for the moment 
So as already mentioned I saw the offer via group buy in this forum and thought give it a try since also prohashing.com announced to offer an X11 multipool.
Ordering:
I ordered the miner during the Chinese holidays directly via email. I had few questions to baikalminer.com. Although they stated several times the response time could take longer than usual I got the response every time within few hours. I got my questions clarified, got the BTC address and paid with my hardly earned BTC’s.
Shipment:
The shipment was super-fast to Europe (Switzerland). February 3rd – 7th with DHL. I was on short vacation and postponed it to February 9th. The usual issues with DHL when getting an SMS at 07.30 am stating the delivery will be between 2pm and 5 pm and 15minutes later the doorbell is ringing… 
Unboxing:
The miner comes in a padded parcel which is not bigger than the dimension of the miner itself. The dimension of the miner is 140mm(L) x 100mm(W) x 355mm(H) and the weight 1650g according to the official website from baikalminer.com. It actually comes with all the needed wire. You have a wire with four single power plugs (to feed four units) at one end and on the other end a PCI-E plug which you can connect to a PSU. Alternatively you could buy four separate four power supply 2V/5A which I think I will buy going forward. Currently I am feeding the quadruple through a PSU from an open rig.
The other bunch of wires which got delivered is for connecting the four units together. The following video did help me to setup the miner properly. https://www.youtube.com/watch?v=0z8QxuULLlU .
After that I had just to plug in the Ethernet wire into the quadruple and the miner was ready for its first start.
Initial operation:
I was very surprised that the first start was a success. Every unit has three led’s. A red led (assuming is the power led), a blue led which is blinking during the start-up and in the middle of the two a smaller green one which is blinking from time to time (assuming traffic light).
The miner obtains its IP through DHCP setup from your local network (I didn’t find an option so far to assign a static internal IP address to the miner though – maybe through terminal option within the GUI?)  Typing the IP address into a browser brings me to the login page where the standard password “Baikal” is needed.
Now I am into the GUI to communicate with the miner. It has 5 tabs – current miner overview (temps, pool information, hashrate per unit etc.), miner (pre-defined pool information, but also the possibility to enter your individual pool information and some sgminer options), settings (timezone settings, web password change, email alert and some options on remote control functionality), backup (backup and restore options) and terminal (self-explanatory).
Currently mining for approximately 10 hours with almost steady 600MH/S on X11 and quark coins. So far no issues and stable operation of the miner…tbc…

Let me know if you find that review useful or if you have any questions I could answer.

Thanks again Baikal for supporting this forum and Bittawn for setting this up! 

Just a reminder to everyone if you purchased a miner through this group buy and are happy with the transaction then please remember to post a positive feedback and a positive trust review.  This trust rating helps us all to know if it is safe to transact with other members of the forum. 

Just wanted to note that I just purchased a few Quads from them over email this past weekend.
Already have tracking, and its stating delivery time from CHN -> USA is three business days.

I didn't even know about the group buy, but was afforded the 10% discount and an allowance for customs.
Pretty good CS off the line!

I've seen the posts on Reddit re: 28nm Baikal ASICs, but delivery looks to be Q3/Q4 2017 if that.

I'm okay with 280 Day ROI given we might see a run on Dash.
20% Returns are +1 in my book.

It does not make sense to buy them if relation price/performance is much worse than quad version.
Relation price/performance must be at least the same.
Also giants are noisy.

one thing i have noticed though, the giant price was not decreased as much as the mini/quadrupel price

mini 500->300
quad 2000->1200
giant 2980->2380

it should be 1780 (6*300 -20)

will probably only get quads if it isnt reduced as the others as i get two quads for the same price as of now

Baikal will be telling the forum about the updates to this group buy next week.  If you want more details right now you can reach out to them directly through email and they can tell you the details for the group buy.  They are still on holiday, but they were replying to me this week.  Workaholics over there at Baikal! LOL

I am a newegg reviewer my cost was zero. If you read the link you can read my review.

Buying this board in bulk to mine is not what I would do.  Given the board to review I maxed at 5 cards.

So people would know if the z270 chipset goes past four cards.

Thanks for the heads up.  Please keep us posted.  What is the method of payment for this group buy?  Are we paying Baikal directly and they are shipping directly to the customer? 

Find a common minimum for the two RX 470's and a common minimum for the two RX 480's that they are stable at individually. Then, use a third party tool like watttool to set the clocks instead of using wattman.
Also, try to lower core/mem clocks by 50/50 each and check stability, repeat till stable.

I just ran across this thread for the group buy.  Is it too late to get in on this group buy?  I just fired an email to Baikal asking, but wanted to see if you guys knew if it was too late or not to join in on this.
