I really wish we could get a clear picture of the size of board with heat sink attached and a template for the mounting holes in the board...Maybe I missed it?...but need to know depth with sinks on....if anyone knows yet?

Hey MMNC. I am working off of Steamboat's board info for dimensions of the heatsinks and such: http://liquidsyndesigns.com/shop/klondike.html
With heatsink, fan, and standoffs Steamboat's k16s are approximately 4"x4"x4" (10x10x10cm)
If we take off the fan, and subtract the length of the bottom standoffs, it looks like it's going to be about 2"-2.5" thick (including the PCIe connector).
It's approximate of course, but I think relatively close. On BKK's thread they talk about using heatsinks ranging from .75" to 2" thick. Standoffs are cheap from Grainger, so I bought 200 2" hex 4-40s.

Hey KL,,, FYI, so I just created an account with Grainger Etc...and went to check availablity on items and I realized, I have a Grainger store up the road 20 miles in Wilmington!! so ill be going there tomorrow (WILM) to pick up a GPU for one of my old miners, and am going to swing by and pick up the feet and standoffs you recommeneded in you hardware list,,,all for $2.65 + tax...lol SWEET! I never knew about Graingers??? lol,,, Thanks again for the info! I really appreciate it..

Glad I could help! I was planning on buying standoffs and feet from a seller on ebay, but I thought that $10 for 40 standoffs was a little pricey. I did a search on google and Grainger came up. I was really surprised by how great their prices are. Did you check out the pc parts supplier I cited for your PCIe splitters? .99 each is fantastic. People are charging 3.99-6.99 a piece for them on other sites. Exact same parts, but $3+ cheaper. I ended up ordering 30 just in case. I have 14 k16 boards coming from Steamboat in addition to my terrahash boards, but his ones come with splitters. I figure that it's good to have some extra splitters on hand in case some are duds.

Hey KL. yes i have had an account with PC Outlet for sometime,,,,fotunately I have like 10 splitters from building Gpu Miners...lol, ok, I am going to graingers today and used you links/part numbers to identify standoffs,, may post a pic later of em!! thx KL

Also, the shipping cost is crippling! $400 to the Uk, that's just not right!!?

Does anyone have any idea of the customs charges I may have to pay on it?

If terrahash will declare full cost of devices which was sent to you(i assume they will)
VAT will be applied to original amount of invoice (not sure how much it´s in U.K., but in Spain it´s 21%)
also some custom processing fees will be applied too.

I will recommend you switch to hosting instead, this is what i done, because custom can take up to one week(here in Spain it´s like this, not sure how it works in U.K. but i guess not really faster)

My personal decision was made on idea that i will exclude extra charges from customs, plus i can start mine earler on hosting so this will give some extra income, as time in this case have big influence, to much hash power will be released during august-september.

If you go with the heat sink labeled #4 on the BKK thread, you are getting good passive heating and much better temperature with fan cooling- around 45 C. I modeled that heat sink and posted it in another thread. I think, without a fan it was keeping temps around 80C. I did a model with a fan blowing over it but never posted the results.

I also modeled the Steamboat design, but said I wouldn't release any specs. Are they selling that design as the one in that link?

With a fan, the steamboat design did pretty well, but its passive cooling isn't excellent due to the small spacing of the fins.

In regards to ETA, are we still looking at August 15 to have our orders?

Here is a link to the heat sink design I mentioned above (not the Steamboat design): https://bitcointalksearch.org/topic/m.2631164

Wow,,,,what a difference 20 mm makes!

Thx

Extending the fins by about 20 mm has reduced the temperature to 78C, approximately a 50% reduction in temperature.

The key to good passive heat transfer is surface area and large enough fin spacing. Use that heatsink I modeled as your standard. Passive cooling is helpful if one of your fans fails. I guess you could have an auto shutoff at a certain temperature, but...

I was hoping to see pictures and specs of the DX Mini case by now?

Especially as all of my support tickets (3) regarding a refund for my case have gone unanswered. So presuming that I will not be getting a refund for said case, it would be nice to see what I will be getting?

Ya probably no refund without a lot of pressure....but, if your order is filled, it would be nice to have the case and all within. I didn't order a case as I was trying to make the most of my budget and put it all into boards for now. eventually I will order a case most likely. I assume the mini will look like the large only smaller....

Yeh, I had a tight budget to stick to and wanted to get as many boards as I could, but it just felt safer to order a 'plug and play' type device! I'm no Bitcoin noob, but maybe a bit of a computer tech novice and at the time of ordering I didn't want to get involved with the actual construction of the rig, whereas now I feel like I'm a lot more clued up and could handle such a task!!

Also, the shipping cost is crippling! $400 to the Uk, that's just not right!!?

Does anyone have any idea of the customs charges I may have to pay on it?

Hey KL! thanks for that, I will look at grainger as well, I had found some standoffs on amazon, but not was i was looking for...2" is what i want. Cool beans! Thanks again KL. ( the k16's are smaller than I had been thinking) so the k64's should be 8x8"
PS: I did see your hardware list you posted the other day, very nice list....just hadn't pursued the standoffs untill I maybe new the depth with heatsinks.... but the 2" should cover any final senario's

Edit: Just checked out the cooling link, after making another coffee lol, I really like that fan/heatsink set up! Now we are getting a better picture here... TY

Hey Bargraphics, I second the computer history museum and if you like Italian food be sure to visit Joe's. It's by the museum if memory serves me right in downtown San Jose.

*EDIT, I got the computer history museum confused with the Tech museum. Joe's is near the Tech Museum and it's called "Original Joe's Italian Restaurant".

just checked out that link! that we be awesome to see. i love that kind of stuff....sad part is,,,i can remember actually seeing a lot of it in use,,,lol

Thanks for the update. Will the hosting services be ready to go as soon as the boards are assembled?

Yes it will be. We will be starting another thread to take recommendations or vote on which pool to use etc.

Is it time for this discussion to begin?

PLEASE get a board template for mounting holes/standoffs and the thinkness with heatsinks attached, and the exact dimensions of both boards...I know k64 is simply 4 k16's but.... and I assume sinks are on the back side opposite of the pci-e connecters etc.... but find all that out,,,and what the boards are actually hashing at last check :
THX! Good Luck
