Topic: antminer s1's on a rack (Read 3252 times)
I have to say that you've done an amazing job! If I didn't already have my S1's "mounted" in a 4U case I would be all over this. Sure beats a makeshift setup and a ton of zip ties that's for sure.
looks nice, two suggestions:
1) KISS. Make the front and rear identical, similar to this image. might not rack as nicely without bottom/top/sides, but allows clean 3-wide builds
2) Re-design it so that 3*120mm fans cool 8-10 blades packed more densely. This would be terrific for those underclocking to 150GH/210W.
Here's the implementation of the above for the S3.
Also can be for S1.

Seriously, that is beautiful.
How loud is the bank of Deltas?
They sound like a jet getting ready to take off:)
They are UHE spec, about 102 CFM at 7500 rpm, 62 dBa

Nice! The front plate looks pretty thin, will it carry the full weight of a loaded case?
This is a prototype, so the answer is no.
It's only 0.794 mm thick.
I'd beef it up or use a fixed shelf rails.

... so pretty! Now the question is when will Bitmain Tech be sending you a proper thank you in the form of BM1382 hash panels to test if the S3 format works (It totally should)
OK, I got it all together and hashing away.

Dropped temps by 10 degrees C on overclocked S1s.

This is a prototype, so there are some holes missing, cables aren't tied up etc.
Don't judge:)
According to Antminer S3 dimensions this will work with S3 as well.
I will be starting for sale thread shortly.
I can make any configuration, i.e. 120 fans in rear, 80mm fans near blades, non rack box for blades only without PSU etc.
Shoot me a message or post here with any questions.

Parts are arriving today.
looks nice, two suggestions:
1) KISS. Make the front and rear identical, similar to this image. might not rack as nicely without bottom/top/sides, but allows clean 3-wide builds
2) Re-design it so that 3*120mm fans cool 8-10 blades packed more densely. This would be terrific for those underclocking to 150GH/210W.

Completely agree on KISS principle.
However:
1) Where will the PSUs go? My goal is to have an "enclosure" to help with cooling of overclocked units.
If they are underclocked then we don't need all of those extra fans.
I have 3-wide (6 blades) design ready, although my goal was to increase density.
2) I can fit 2x120 fans on the rear wall with 2 PSUs or 6x80mm fans with same.
Unless some 60W 65 Db 120mm Delta fans are employed I can get more CFMs with 6x80mm fans than 2x120 with less noise and less power consumption
If only one PSU is used (lets say 8 underclocked S1 blades and 1 PSU there's still no space for 3 x 120mm fan in there.
As far as the number of blades, it is geometrically impossible to fit more than 9 blades in 19" wide space without modifying heatsinks or loosing side walls.
Not very clean as you mentioned
Now, if we go to 7U it is possible to mount 18 blades so that would give you 9 S1s in 7U space.
Also, the PSUs can be mounted with intake facing inside to help remove hot air.
That would simplify side wall.
However, I am concerned with PSU getting 45+ degree (C) air from the blades and getting too hot to maintain adequate output.
If the units are underclocked then this would work.
its also good to keep in mind that (from the KISS angle) a lot of S1 users that may be looking at undervolting for a higher density (such as 8 blades in a 19" space) and using server power supplies which can be operated on other shelves or have 2-4' leads (appropriate gauge for the length/amperage of course). The 1_1_1_1 photos in the pictures thread are a good example, where he has a crammed-looking setup of 3 S1 units jammed side by side in a 19" width. with 4 units undervolted slightly on a custom front/back plate it could be a slick and easy setup.
As long as you're designing rack components, maybe think about adding a waterblock setup instead of air cooling them.
One large pump takes less electricity than 20 pwm fans, and you could pack more blades into the rack.
14mm water channels with a blade mounted on each side.
Aluminum is easy to mill, but you could also use steel with copper pipe.
If you do use steel, extra time will be needed for lapping the surface.
Cheers.

not worth it imo. its a lot of weight and added complications spent on 2w/GH (or even 1.3w/GH) hardware when 0.5w/GH hardware will be here in two months. You would spend about $40/antminer on a custom waterblock that would likely not be reusable (except for the unnannounced S3???) after the miners are liquidated/scrapped in a few months.

Looks good. When will you have the prototypes done?
About 10 days

A form of machining (I was thinking of EDM wire) but it may be overkill if that's aluminum. http://en.wikipedia.org/wiki/Electrical_discharge_machining
Oh, I see.
Prototype is being made out of 6061.

Very nice. EDM could do the delicate work of hollowing out the BTC.
Picturing it lit up with leds now...

What's EDM by the way?
