Now that the mining hardware has matured to where all of them ship in there own case, I thought it would be a good idea to offer server rack frames for mining equipment and quiet server/mining cabinets.  

Made from slotted aluminum extrusion, this unique material offers the possibility to build 3-4 layer side panels and to be very modular e.g. easily increase depth/height of the rack by simply adding "modules."  

Here is a model of a 8U frame (these could be built at any U height):

With an SP10:

All comments/suggestions are appreciated!

Thanks!

This sounds very cool, i'm sure that at the right price, lots of folks would be interested. When will you complete a prototype, or are you just gauging interest for now?

Thanks.  I should have a prototype later this week.    ;D

I like that you can customize the U size so it can be as small or large as you would like.

Since it's going to be a quiet rack, how will you deal with ventilation? It obviously has to be enclosed to be silent, correct?

How much noise reduction you plan to achieve? I am very excited, cause I am in active search for an affordable but good silent rack. What about heat?

Interested!

It would be nice with an sp10.  drop the sound 10 db and your gear would be just about perfect.

Realistically do you think you will be able to offer a more economical solution than just going on eBay and getting a standard half rack for $100-$200?

Completed a 12U prototype:

The two inner floor beams and four posts can all be re-positioned.

Awesome!

For a quiet version you might have to stick to a set size, say 24U. That's because doors and sides would be hard to add in a modular fashion.  Need floor, two sides, doors (two front, two back), top - all with sound-proof lining. Air intake through front door, exhaust out top of back doors. Fans built into back doors. All as a suggestion.

I built a second, slightly taller prototype, in order to be able to use some extrusions to support odd-sized mining equipment, without having to purchase expensive server cabinet shelves.

The locations of all of the posts and beams are fully adjustable.

I still need to build "quiet" panels...

Good news...Manged to get a 10dB reduction in noise by applying 1/2-inch thick sound barrier to the top, front and sides.   :D

Interesting, any pics? When will you finish working on this project?

A suggestion: you're going to need to start planning how you will manage thermals in this thing, it's not something you're going to be able to tack on afterwards. Essentially what your proposing is an insulated box that will cover the miners right? Like a parka in July. You're  probably considering this already, but thought I'd mention it in case you weren't.

As far as thermal management goes it's very doable - here's the approach of one company : http://www.pathfindersystemsdesign.com/wp-content/uploads/2012/06/towercool.pdf it looks fancy, but at the end of the day it's a simple matter of cool air in and hot air hot.

Pics some time over the coming weekend.   ;D


These are very modular, so its very easy to add a thicker/ducted door, or add an exhaust hole on the top of the rear door (which I'm currently planning on doing), etc.

First pics!  (Pardon some of the protective paper).   ::)

Fresh air enters the cabinet from the bottom of the front door and exits out the top of the back door with a -10dB in noise.

This 8U quiet cabinet would be perfect for 2x Spondoolies-Tech SP30.   ;D

wow that looks nice!  Any idea on prices?

Thanks!

Estimating the price for the quiet server cabinet to be around $1100, plus shipping (flat-packed) from New Hampshire.

Cool man, this is exactly what one will need, to run some SP at home!!! I liked very much the idea with the vent duct, thus you can remove the hot air from SPs directly out from building. Does it come with a blower?

I made noise cancelling panels with HVAC fiber ductboard.I installed them in a restaurant that had hard wood ceilings & concrete floors,it only took a few well placed panels to stop the echo  ;)

I cut all edges at a 45 degree angle & sprayed glue on the fiberglass side & applied a fabric to it.That keeps the fiberglass from flaking off & gives a classy look.

The other side has the silver aluminized facing which is kinda tough.It can be punctured/scratched/ripped though.You can paint it any color you want.

Each sheet is 10 ft x 4 ft x 1 inch or 1 1/2 thick & costs about $35 a sheet.

Just an idea  ;)

Can you please post some photos as well? Sounds very attractive :)

It will not include a blower.  You local home improvement store should have 'em in stock. 

A quick video demonstrating the effectiveness of my quiet server cabinet:

Spotswood, are you using 80/20 parts for the frame?

Certainly looks like 80/20 parts I have seen in the past...

Its made from aluminum t-slot extrusions, not 80/20, but another vendor.

Sorry,but I lost the pics when a HDD failed a few years ago   :'(

You can use ANY fabric you want almost,it needs to be abit porous though,to let the sound in,otherwise it kinda defeats the principal  :D

The panels were 3 ft x 4 ft & a few were 2 1/2 ft x 6 ft.You could make them almost any shape,just need to work the fabric around the curves,can be tricky  ;)

My customer had a carpenter come in later & put them in wood frames,it turned out really nice!! Wish I still had those pics!!!  >:(

I'm now ready to take orders for this 8U quiet server cabinet.

I'm working on this kind of cabinet too.
To have better performance with the noise reduction you could use foam for the wall and sound trap for the intake and outcoming air.
Below and example of a sound trap.

That looks awesome.

This current design attempts to strike a balance between noise reduction and cooling (with more emphasis on cooling atm).

Looks like a great product.  I love the sleek design.  Do you mind taking a picture of front exhaust?  I'm curious what it looks like.

I don't have interior pics just yet, but here is the model of the front door.  The interior is lined with sound absorbing foam.  Air enters the cabinet via the open bottom.

I believe that making the door the way you intake and out take the air is wrong (it seems good on professional product tough). It require to much work and precision to make it effective.
After thinking about it I plan to make my sound traps in the cabinet and I want to it to be removable and cleanable.
To me, the best is to make big hole and use this component to connect the sound trap with the interior and the exterior of the cabinet.

To make the soundtrap, I'm thinking about using plastic box with foam in side. To break the sound, polystyrene plate with foam stick on it. I may have 100% sound reduction :D

What is the program did you use to make 3D model ?

EDIT : this is what i think of :
then all you have to worry is make sure that air does not go out or in from doors. The most of the noise will come from the air flow

It would be useful for many customers as the sale thread for the server rack frames are up now. As there is custom size frames are available many people would be interested in this deal with this reasonable prize. Can you guide me to your services page where I can get more info about the kind of fields you handle?


Thanks
