MY LATEST UPDATE:

Got my new electrical panel all installed -- the electricians did an awesome job on it.

So far I have 12 of the Dell R815 servers running... 24 more of those to go & alot of cable organization on the back side (haha).

Then I will be putting together as many additional HP Z400s as I have GPUs for right now... B&H cancelled almost my entire back-order of 1080Tis from December when the cards finally came into stock last week so that has left me a bit shy on cards that I planned for (they delivered 2 out of 18 pcs... after 5 weeks of waiting). I should be able to get another ~18 systems online, though, with the cards I stocked up on in November / December.

I'm installing a main lug in my basement to bring in 240v for my antminer a3. I just popped open my main breaker for the first time and I can say without a doubt I wish the electrician who did the initial wiring would have made it as organized as yours did hahaha.

Also, why are you using shelving instead of racks? Seems like some racks and pdus would take up much less room.

3 phase power?

Were you able to pickup that pallet of z400s?

I didn't end up going after it as I can't get enough GPUs to justify it. Just been snapping up the cheapest Z400s on e-bay.

But yes it is 3-phase 240v coming in broken out to 120v circuits.

Any idea why B&H cancelled your back order?

They made a lot of claims... such as MSI cancelling part of their order, MSI making the limits, etc, etc.

IMHO it's all BS... and they didn't want to give me the price.

Its probably worth it only if you have PCIE slots and put few GPUS in parallel in the same machine.
As a supplemental mining

Not very efficient. Oh well, it was a fun experiment.

I went and found the $230 one on my own with only the TDP information you provided. God damn lol that googlefu.

Ya, i was tossed on it because it's a blade as well. But, at that price...

I'm more in need of systems with PCIE 3.0 slots. But, if I had 5MW of power I didn't know what to do with...

Found a good deal on ebay for some cpu miners..

2.1Kh/s ready to go for $300 at 420w cpu tdp -- There's like 100Kh/s worth of cpu miners available..

Trying to decide if I should tell you guys about it or pull the trigger myself Undecided

Buy however many you want then share, haha =)

One of those sellers also has 32 m910's without cpus (or 2 cpus only, hard to understand the guy, he was on mobile).

Its a blade so it cant run standalone.... youd have to buy an enclosure as well, so thats going to put a LOT of people off.

Wow. I thought I had found a great deal - 550hr for $150....

These aren't exactly plug and play, you'll have to know what you're doing with servers and linux to use them. But, if you do, there's a lot of stuff out there. You can build a 40gigabit network in your house for a couple $100. Or a 100gbit network for < $5000. I like trolling for the latest infiniband cards to play with.

You'd have to buy them all to get it at that price (did some negotiations with the seller). Otherwise it will be closer to $420. (prices don't include shipping).

Don't think your GPU has enough ram to do much. You can pick up a rx550 or 560 fairly cheaply and start that way. Later change out your mobo and processor to get more hr.

for that much $, get yourself a used dual Xeon *that supports AES* and start CPU mining. Once you get a little more green, add a gpu or two to it.

Your gaming machine - does it have PCI-e slots?

Looks 1x PCI-e x16, 1x PCI-e, and 4x PCI.
