DETAILED MINER DIMENSIONS AND DESCRIPTION:
Each miner is basically a cylinder consisting of a: (1) a round heatsink (95mm diameter, 45mm height) on the bottom, and (2) a round fan on the top (95mm diameter at the widest point of the rims, 25mm height). For one mounting possibility, there is a 14mm wide indentation (2mm deep), around the circumference of the fan. The lower rim of the fan (before the indented area) is 4mm in height, and the top rim (before the indented area) is 1mm in height. There is a small slope (bevel) from each of the upper and lower rims to the indented area (note that I did not include the beveled area in the measurement of the 14mm width of the indentation). The fan is secured to the heatsink with four triangular mounting tabs that protrude 8mm (at the longest measured from the edge of the rim to the point of the triangle). Each "side" of the triangular mounting tab is 14mm in length. The angle between the legs of the mounting tabs is 90 degrees. Viewed from the top, therefore, the mounting tabs form the corners of an 80mm x 80mm square superimposed on the otherwise circular shape of the 95mm fan. Each miner requires two connections - a power wire and a USB wire. These connections are located together (about 45mm apart) on one side of the heatsink below one of the mounting tabs.
(A) A single module should be designed to secure at least one, or at most two, miner(s). Multiple modules must be capable of being joined together to form a structure.
(A) Basic design should form a stable, standalone structure with a minimum of 10 modules (10-20 miners per structure).
(B) The design should accommodate an internal, protected, location for 2 high amperage power distribution busses (one positive, one negative) like Blue Sea Systems 2312 or similar, in a location that is protected from accidental touching (kids, pets).
(C) Efficient, aesthetic and easily managed routing of power wires from each miner to the power distribution strips; and of each USB cable to a USB hub (may be external to design, but routing of cables is part of criteria).
(D) Ease of assembly (multiple parts/prints are okay and are probably required).
(E) The delicate heatsink fins should be protected once the modules are connected to form a structure.
(F) Airflow around the heatsinks should not be impeded.
Readily available non-printed parts (such as threaded rod to create clamps to hold the fans) may be used, but ideally most of the design should be printable.
DESIRABLE BUT NOT REQUIRED - ADDITIONAL CRITERIA
(i) Expansion should be possible by connecting additional mining modules and/or joining sets of mining modules, up to 20 modules per structure.
(ii) The structure would ideally also enclose a power supply that is 8" x 4" x 11"
Designs that require laser cutting or larger than 175mm x 175mm printing.

I have marked with 5 stars all of those designs that met my criteria. If you are interested in my "bounty" and have a 5 star design please make sure you send me your public bitcoin and litecoin address.
Thank you everyone for the great designs. This is my first time posting a competition, and I will definitely do it again!!!!

I may turn my preliminary design into production drawings if you are interested

There are some examples around of a whole PC submerged in this kind of liquids for heat dissipation.
Using this solution you may get rid of those noisy fans while having as much ASIC boards as you want in a "fish bowl" made of crystal plastic.
If you are interested I may do a design with this concept.

Bounty for each unique solution, subject to rules below:
0.025 Bitcoins
1.00 Litecoins
I may in my discretion make larger awards especially for a notable and superlative design that does not otherwise win the cash award (e.g., a notable and superlative second place).
RULES:
You must send me your public bitcoin and litecoin address (a "receive" address) to be able to get the bounties. You can send this by PM if you prefer or post in a comment (note that the architecture of bitcoins and alt-coins in general is such that the public address cannot be used in any way to undermine security since your private wallet keys are the only thing important to keep private - don't send me that!!).
A "unique" design is one that is not similar to any other previously posted design. A design variation (horizontal versus vertical, rotations, aesthetic changes, etc.) does **not** make a unique design, although such variations are always greatly appreciated.
A single person may receive no more than 3 such bounties (assuming 3 unique designs). Again, I appreciate each and every design but this is not intended as payment, more as a fun add on and I don't want one person to take up all the bounties.
I reserve the right to end the bounty if there are more than 15 unique solutions that are paid bounties. I may continue to pay the bounty after that, but it will be solely in my discretion. FWIW, I am trying to protect against someone submitting many designs that would require payouts far in excess of what I had planned. I will be fair about this, and if I cut off the bounty after 15 I will let everyone know here, and I will still consider paying bounties for someone who had work in progress.
I will be the sole judge of whether an entry meets my requirements, and my decision in that regard will be final. This extra bounty is not enough to argue about so please don't!

There must be some place for these 2 power busses in the design (placed near enough to each other that a single power wire from a miner can easily be split and hooked up to both busses).
I am okay with an alternative bus for power if your optimal design requires different size/shape. If you choose to incorporate a different bus, please specify the model and make of the bus, and make sure it is rated to handle at least 50 amps continuous (at 13.8 volts), which is the approximate amperage of 20 miners at full load.
NOTE ALSO THE FOLLOWING ALTERNATIVE TO REQUIREMENTS: 2 or more structures may be used that **collectively** would support up to 20 miners ... and in that case you could use a design with one power supply and one common set of busses shared amongst the structures. For example, 2 structures each containing 10 modules, that are joined together with central power supply box and power bus that is incorporated as part of the design. This just occurred to me and it is an acceptable (and possibly better) alternative to a single structure that can be expanded to 20 miners. Ideally, such a multiple structure solution could be further expanded with an additional power supply (and one to two identical structures added on) to 30 or 40 modules. A full blown mining operation will involve 100 or more of these miners, so the concept of easily adding on to the "farm" would be nice (but not required to be so expandable, just a plus).

each miner has a standard mini usb cable connection which will go to a hub (I did not ask for incorporation of the hub because there are too many shapes and sizes of hubs and I have not yet chosen a single hub ... so assume the mini usb cables need to run to an external hub located near the base of the structure ... or better design a platform for a generic but large 10 port hub and make sure either way that there is room to route the usb cables to it.
Each miner also requires a power cable, which is really 2 wires (positive/red and ground/black). All of the power wires must run to the high amp busses each about 6" long and 1" wide. The power wires connect to the bus with screw type terminals.
