Thanks for the input, everythings still very tentative till the design is finalised then I can start to shop around.
It'll be interesting to see how fast we can get these boards put into action.
I can't imagine the components being too much cheaper than mouser but would love if they were.
Hopefully the through hole components don't affect the overall assembly price too much.
If anybody knows any good assemblers or a place to get the heatsinks domestically I think we could all benefit.
I am going to be water cooling mine, I have not worked all the details out yet but it will be simple using off the shelf parts.
I have an avalon now and it puts out a lot of heat and noise.
Here is my initial idea. Its looking like I will need to make an adapter plate from flat bar and will mount broads both side of the tube.
https://bitcointalksearch.org/topic/m.2187398I like your idea, it looks to have a lot of promise, particularly for cooling as many boards as mine.
Is there a u-bolt that would suit the holes on the klondike?
Also would the fact that there is a through hole component make it infeasible for the klondike?
I don't quite understand what you guys mean about surface area.
Are you talking about the interior surface area that is in contact with the water?
Also instead of the nozzle, maybe you could consider something like this:

All you would need to do is weld the cap on the end, then drill a suitable hole and tap a thread inside it.
I would trust a screw in, more than hoseclamps, even though the pressure probably isn't that high so it may not matter.
Also you could place the holes on the top rather than either end which tom_o was suggesting.
Just an FYI ... I live in Sydney
So if you want to ensure continued support by the cgminer devs - ckolivas and myself - if you can provide one to each of us we can of course ensure we can provide proper and ongoing support for them.
The Avalon software is already under heavy development by ckolivas at the moment for the switch over to USB.
... and being in Sydney myself ... you can get one to me the same day they are ready and I can test and work on cgminer if required to make sure everyone will have it working as soon as possible if there are any problems then and in the future
ckolivas lives in Aus also
I would probably be agreeable to donating a board or two in exchange for some advice setting up cgminer on my host.
I'm a bit hesitant to make any concrete promises at this point though without even a finalised design.
