I have a fair number of Avalon A6's that I'm selling - most have been in use since they were initially released, and all work flawlessly.  They've been housed in a temperature controlled environment, although in the winter that basically means everyplace - and they've been run exclusively on 240v server PSU's.

You can see the action shots here:

and here are some of them running in one of my plenum's:

I'm selling them for 1.9BTC each, INCLUDING shipping - I only ship in the domestic US, not Canada or International (sorry).  Price is non-negotiable, and is for the Avalon A6 itself and the link cable, so you'll need either buy the Pi+usb adapter or already have an Avalon A6 to chain it off of.  For anyone who buys 8, I'll include a Pi+usb adapter, so you'll have a fully functional rig (this was the configuration I ran them as).

If you want to buy one, then act fast because I suspect they'll sell quickly, I only will accept BTC, and everything escrowed through OgNasty (buyer pays escrow fees) - no direct BTC to me, so no scammers pretending.  They'll ship within one day of the escrow being ok'd by OgNasty (so sometimes same day, depending on whether we get it in time).

PM me if you have any questions, or start the escrow through OgNasty and PM me if you're only buying a couple.  I'll keep the thread updated so when I'm down to my last 10 or so, then just make sure to contact me first.

You have the nicest looking setups...

And the best escrow service!  ;)

Really nice setup.  Did you ever decide on selling a 2880 fan kit?

Awsome !!!

Good luck with the sale.

Whoever buys from MarkAz, don't worry about getting hosed. He is an honest guy and keeps his gear nice and tidy..

Thanks!  ;)  The plenum design works wonders for managing heat...  That's actually the 'v2' version, my 'v3' rack is slightly different, and makes it so it's possible to remove machines individually - with the v2 one, I had to remove any machines to the left of the one I needed to remove.  Thankfully the Avalons have been really reliable, so it wasn't an issue working with them, but with the S7's it was much more of a pain.

As far as the fan kit, I've thought about it, but haven't had time - as you can see from the setup, I run two A6's per 2880W, so there's a fair bit of headroom on the PSU, and the 120mm fan is PWM with a thermal sensor set on top of the hottest portion of the PSU.  With ~2200w load, the PSU isn't silent, but it's definitely more on the quiet side than the loud side - and it's night and day different from the stock fans.

Just to add to the sentiments here you can definitely buy with confidence from MarkAz. He sold me my first Bitcoin miners, S5s, and they have been a dream to own with his laser cut mods. I was new to the Bitcoin schism and he answered all my noob questions via PM and never with a sense of grandios since he was an OG to BTC mining as I call him lol...or is that OBTCG (Original BTC Gansta lol) You run into these egos all the time when dealing with others, but not with MarkAz.

Since I was purchasing with FIAT he allowed me to use Escrow.com which I haven't found anyone on the forums that has been willing to accept. I also trust OGNasty whole heartedly as he has saved me from a few scam attempts since my start in November. In my opinion you cannot go wrong using these two. OGNasty responds at lightning fast speeds and MarkAz delivers as promised. How can you ask for anything better than that!

Very nice design! I know you mentioned non-negotiable but given the next diff of 20%+  and no end in sight along with flat BTC price, I'm interested at 1.5 per miner. Just figured I toss it out there in case you don't get much interest at the 1.9 price.

Thanks for your consideration,

There is a group buy for 2.3BTC so his price is fair considering its not 0.50W/GHS equipment.

I'd like one or two A6 but where do you find the USB adapter? I already have a Raspberry Pi.

You can buy them from any of the Avalon dealers, like Zoomhash or from BlockC directly - they typically sell the Pi+case+controller+power supply together for $75, so figure the controller is probably ~$20.  Then just flash an SD card with the Avalon firmware and you're in business.

As always MarkAz your setup is awesome!  :o

Great job man. Sad to see that you need to sell them. I guess the diff upgrade kill the project.  :-\

Thanks!  Actually it's primarily problems with the landlord at our second location, but the difficulty just gives us less of a window to make other plans.  These baby's need to be running to make money, and right now they're just sitting in boxes.  Poor little guys... They just need a new home and some love (and by love I mean power)!  ;)

Sad you dont ship to Canada. I will check if I can get them shipped to somewhere in US. Will let you know.

Yeah, sorry about that - I've just had too many mixed experiences shipping outside the US, customs is just too fickle, and I hate that they send you bills for things weeks after they arrive.

Purchasing 40 units per agreement with MarkAz

There's still about 15 left, but they're moving fast!  :)

pm sent

At this point it looks like they're almost all sold - so if you are interested, contact me first before starting escrow with OgNasty.  Once I ship out the ones today and go through them all, I'll post how many are left.

I sent a pm

I have 6 left, 5 with philipma's purchase, so if you're on the fence, now's the time to get off it.  ;)

PM Sent for two.

ahahaha you could not resist.  ;)

yeah looking forward to getting this one.

NOoooo  :'(

What rack are you using?
Are you selling the rack?

 When you ship this to me  please let me know.

this was my tx id to OgNasty

The rack is something I custom built, it's actually both a rack and a plenum, meaning it takes all the exhaust air and isolates it - but you still need to have extractor fans to 'pull' the air out.  Works REALLY well, as long as you make sure the exhaust fans have enough static pressure.  It actually has a manometer on it that shows the pressure differential between the room and plenum, so it's really easy to see if you need more fan power or not.

The v2 rack you see in the pictures handles 32 miners (4x8) - my v3 rack, which is the same physical size, handles 40 miners (5x8), and is pretty much the limit as far as density goes.  The rack itself is about 6 feet tall, 3 feet wide and about 1 foot deep, and is aluminum with fiber board (heat rated) inserts.  The v2 rack requires you to remove a side beam (easy) to remove miners, as they slide in and lock from the side - whereas the v3 then kind of lock in place from the front, making them easier to maintain.

We're keeping most of them, but I would sell either of my test ones (one v2 and one v3).  I suspect it wouldn't be cheap to ship, even though it breaks down into parts and is just re-assembled.  I could also ship it without the fiber board inserts, which you could just get made at home depot, and that would probably drop the shipping cost considerably.  If you're serious about it, then feel free to PM me.

Yup, it will go out with the others tomorrow, and I'll PM the tracking number to you!

Thank you

They're all gone, thanks to all that picked one up.  If you missed out on these, and you're interested in some new in box Batch 6 S7's, I have 14 that I'll be posting up probably today.  I'll be selling them for 2.15 BTC shipped, which is effectively the same $/GH as these A6's.  PM me if you're interested!

I also think I'll have a couple RPi's and USB controllers, so if you're interested in those I'll be posting about them as well - not sure how many there will be (probably 6 or so), but I'll probably be looking for 0.15 BTC each for those (shipped) - and I'll also have some of just the USB adapters that anyone buying a Pi set can get for an additional 0.05 BTC (I think I have 4 or 5 of these).  PM if you want some, and make sure to say how many you'd want as they'll be first come first served.

my avalon6 has arrived.

I would like to run it over nite then ask OgNasty to release funds to you.  you are DNA d057

the one on the bottom

and you appear to have the best hash rate of all my gear.

Cool, feel free to run it overnight.  Glad to hear it's hashing well - as with all hardware, some run a bit better and some a bit less than others, looks like you got one from the bit better batch.  ;)  In general I found the A6's to be very consistent in terms of performance, and I love how they're designed and work as a cluster.

Oh, and technically it's not MY A6, it's YOUR A6 that has that nice hash rate.  ;)

Got busy with the solar array yesterday.  I sent a release pm today

Would you be interested in shipping entire racks?

Wasn't this sold months ago ?

Yup, I sold them all in the first few days.  :)
