Is this something people may be interested in? I'm mining in an apartment (About 5,000W at the moment, plan to bump it up to ~8200W) using some cheap shelves I purchased at the hardware store. It works well enough, but it could be better.

I'm really interested in whether or not there are modern rackmount units available comparable to the T9+ / L3+ (I know, I know, altcoin, I mine a mix.) My metered PDUs are already on a little 8u freestanding rack on the top shelf, but I could really increase my spacial efficiency with a 42U rack and a big collector / fan fixed to the backside of it venting out the window.

I appreciate any leads or help afforded to me.

Thanks! Smiley

If you are looking for racks that fit the S9 and L3+ I have some 7U shelves that fit in a server rack and fits 3 antminers and 3 psu's. Power and ethernet goes through the front obviously. I can take a photo if needed I had them fully loaded for a while but I moved the majority of my mine so I no longer need them.

The last official rack mounted ASIC from Bitmain was the S4s.  I have a couple for sale if for some reason your interested (not recommended).

Personally, I built custom shelves out of Unistrut that work great,  exactly match my needs, and for 10' of shelves, were actually cheaper than what the equivalent would have cost from Home Depot - and one hell of a lot sturdier.

Mined for a living since 2017.  Dabbled for years before that.

@ taserz

I appreciate the offer; however, I'm looking for something more dense than the breadbox-to-rackmount adapters.

@ tasers & ccgllc

The S4 is really the form factor I'm looking for, only with T9+ chips inside. I like the density on the R4 units.

I.e. http://bitcoinminerhosting.com/wp-content/uploads/2017/01/antminer_r4.jpg

I'd love to help design a water-cooled ASIC solution. It wouldn't be terribly difficult to leak-resist it.

I have other hybrid designs for commercial pursuits, if only someone would hire me or bankroll me. Q_Q

Edit:

As far as density - I have a set of shelves from Home Depot that are about 36" wide by 54" tall by 14" deep. I can stuff 18 ASICs on this shelf and handle cooling and power, too.

I'm currently running 6 of 18 and using about 5,280W of my 15,360W maximum design spec.

Bitfury kinda has a current-gen rack unit but good luck tracking one down to buy.

My opinion, the S4 is the best KW+ miner yet made. Those are good machines.

I looked up the reference design, and I love it. You're right that it's impossible to get, though.

It may as well be vaporware, even if it is ideal. I could run one of these per 30A circuit if I could underclock it slightly to 24A.

"Specs" (supposedly...)

576 ASIC chips
30TH/s - 49TH/s
6.4kW (max) / 27A @ 240V
