    i would be interested in a few bitcoin ones in a few weeks when i pay off my current gear.

    You may want to look into buying those 16x extensions from china in bulk for a good price. If miners could get the base and 4-5 extensions for 100-110 in a kit it would be a hit. right now you have to buy extensions at a huge markup or wait weeks for them to ship from china.

    I worked on the prototype this afternoon (standard ATX size).

    Looking sexy, these could definitely be popular.

    Yep looks great. I think I just found the home of my next MP rig.

    Can it fit a 16.2" x 13.0" MEB motherboard?

    Of course! Here it is with a TYAN S8812WGM3NR:

    Does anybody have the spec. for the standoff locations on a MEB motherboard?

    Still looking but may as well include the SWTX standoff specs while we are at it.

    I would totally go for one w/ a front panel for 3x 120mm fans to blow over my board.

    Spottsworth whipped that up in like 20 minutes between PM's today, mans got skill. I'm in for a 4p as well, if you can find a way to make 120mm fan's mountable along the front/long side of the board even better!

    Please shoot me a pm when details are pinned down.

    Here's what I've come up with for fan mounts. The fans are bolted to two pieces of flat bar which is then sandwiched between two t-slot extrusions.

    Still undecided whether the flat bar should be 6 individual pieces.

    Spots couldn't you just mount them on T-slot nuts?

    Then you could run 80s, 92s, 120s, 140s, whatever would fit. Or people could even bolt up fan brackets (like the Zalman) to mount fans blowing down on the motherboard/ram, etc.

    I think this has been asked already but is there a way to put rack mounts on that guy? Thanks.

    I liked the little strips that could just be held on by a nut and bolt you posted earlier in the thread better.

    Keeps cost down and is more flexible IMO.

    Just get a Norco RPC-470 then just strip out the excess drive bay hardware in the front.

    I was reluctant to do that because the extrusion would block a portion of the fan's intake, but I would include 3/8-inch spacers(w bolts) to remedy that. And even though the t-nuts are pricey, this design would require less fabrication time.

    I don't see a problem with that idea (on a standard ATX-sized tray).

    I could fab and include those just for you. :)

    80/20 is awesome stuff.

    We use it for everything at work! Carts, workstations, desks, tables... we even have a little mini network rack made out of it for our lab.

    for all those waiting for their case from Spotswood, Today I designed a ghetto alternative if you already have adapter cables..
    This should hold me over for a couple weeks till I get my cases from him.

    [​IMG]

    - Motherboard sitting on motherboard box (Which has been inverted)
    - The rack is one of those 4$ soda can roller things for your fridge, I just got out the dremel and cut the bottom roller bar off.
    - User cardboard pieces to make sure video cards remain separated.
    - Cleaned up with Zipties, HDD tied to side, cards held upright, cables cleaned up with the PSU in the back.
    *If you cut the lower rails off, there is just enough clearance to mount cards to the board and have some up top

    A little late I know, but might I make a suggestion? Here's the SSI MEB form factor I posted in the other thread. The green standoffs show placements consistent between SSI MEB and SWTX. The red standoff in the bottom right I'm pretty sure is consistent but haven't been able to validate. So - my suggestion is to include solid standoffs at these locations only and to outfit other areas of the board with flat rubber spacers that are standoff-location-agnostic. This could also make it so that those who buy the MEB/SWTX version could still use an ATX board on it if they wanted to. HPTX is still a whole 'nother kettle of fish unfortunately.

    [​IMG]

    And a question: would the fan spacing in your model be compatible with a 3x120 radiator with standard 15mm spacing?

    Thanks for the drawing!


    As I've come to the realization that all of these "exotic" form factors are all derived from standard ATX, I can relax somewhat, now that (as you suggested) the end-user could mount the board to the tray via the ATX standoffs and then use the remaining standoffs as spacers.


    The fans can be re-positioned all along the slot in the extrusion, but for watercooling, I'd recommend using a couple of these brackets:

    [​IMG]

    Which again, can be positioned all along the extrusion.

    They would have to be removable then - if you have metal ATX standoffs midboard on an MEB or SWTX mobo, it could cause a short. In fact, it probably will since some of those standoffs will be right around the VRMs of a 4P board. That's why I suggested the rubber spacers in lieu of standoffs in certain spots à la HighSpeedPC.

    Those fan brackets look perfect! And if they slide along the extrusion, I could even use my old PA-series rad with the oldschool 25mm spacing. Sweet!

    do we have any final pictures for the 4p ones that have been ordered or made.

    would like to see some.

    Sorry if a bit off topic but anyone think the same frame in plastic would be strong enough? I'm having a hard time to find anything like these T Slot bars in plastic, thought it could be found locally and much cheaper if such a thing exists.

    Even if you found plastic, depending on how you mounted your cards I would be weary.. If you plan on letting the slot lip of the card hold up the front it needs to be something that can withstand high temps.. For my flashed and OC'd 6950, fans on ~80%, the entire metal slot plug cover gets hot enough to burn to the touch.. My 5830s arent bad, but would still likely warp cheap plastic, especially holding up weight..

    Do yourself a favor, Just buy one from Spotswood (So he can make more and possibly lower the price :D)

    The first 4p tray, is 90% done.

    [​IMG]

    [​IMG]



    The 4p-sized trays are drilled with two sets of standard-ATX standoff locations.

    A standard-ATX board for a bitcoin rig would get mounted close to the PSU.

    [​IMG]


    And a MEB/SWX board would be mounted further away from the PSU.

    nice !!!

    will this hold a Supermicro 4P board? or are those holes just for the Tyan 4P board?

    what are the dimensions of the tray & post?

    Thanks.

    The overall dimensions are 16.5 x 23.5 x 9, with 17-inches between the posts in the back. So yes, large enough for a 4p board. :D

    The form factor of the standoff holes are simply two sets of standard-ATX, but because the "exotic" form factors share many of the standard-ATX standoff locations, you'll still be able to fasten a MEB/SWTX board to the tray with a few screws. The tray comes with 1/2-inch female threaded spacers (and screws), so the MB will still be supported in those areas without any pre-drilled holes.

    I know I might be TERRIBLY late for this, but put the hdd on its side and make it hold 2 total hdd's.

    This will decrease the side a bit, but make room for people like me who use their folding rigs for other things as well. Heck, make it so it holds a 3 bay caddy or something like that, so its essentially a 2x5.5" bay, I dunno, just an idea!

    Take a dremel and make your own holes.

    Then you can drill it up however you like it
