That one looks awesome! Great for overclocking Pi3 experiments (while raspi-config won't let you overclock the Pi3 anymore, you can still overclock it "manually" in boot/config.txt)
Meanwhile I compactified my cooling design ... using 40 g potato chip cans and putting two Pi3 in a single tube, cooled by a spare slot fan :-).
One Pi3 crunches 4 BRP4 tasks, the other one 4 GW jobs in parallel. They run at 51 and 55°C respectively. Note the insulation in between the Pis and around the aluminum interior of the cans.
Meanwhile, I tried FFTW 3.3.4 but found no performance gain vs the version 3.3.2 for the Raspberry Pi 3.
Looks interesting :-)
The wireless signal is ok from inside the can?
I understand that the antenna is the yellowish thingy next to the black-and-white flat-ribbon display connector (on the other side of the SD card slot), so here it's not really inside the can but raised above it. Still, the WiFi connection will periodically drop (even after turning off the power management feature of the WiFi ), so I have a script running on those Pis that checks connectivity to the router and, if needed, re-establishes the WiFi connection.
The heat sink on your Pi has much taller fins than mine : http://www.amazon.de/dp/B00W7BXTH6 ... still I kind of doubt that passive cooling will be enough for the Pi3. Please let us know.
Unfortunately the Pi has no heat sink mounting holes to support the weight. Luckily the board seems rather flat around the CPU.
While those heat sinks might be a bit to large, especially the aluminum one should be easily customizable...

I surrender! You win. The PiVE took me ~61 hours of print time over the course of several days. I now have 4 Pi3s for the PiVE but am awaiting more brass standoffs from China before I can complete it and put it online. Should be here no later than Monday.
Thanks. In a few days I will post the Sketchup files for the PiVE. This way anyone interested can load them in Sketchup (its free) and modify/resize/whatever the "parts" to suit their need. Again I should state that the total print time is ~61 hours. But you could print just one cell from the supplied files and add on/join cells later if wanted.

For my Pi 2s I use:
Just ordered my first Pi 3. Rather excited. Want to play with Ubuntu Mate but will most likely use Raspian for crunching.
Do you guys think the Pi 3, not overclocked, will be OK in this case with a copper heat sink?
Your stack looks clean. Have you considered a 5V fan for the top plate and the mid separator plate for cooling. Your heat syncs are quite tall so if you try a fan you will probably need to "add in" some more standoffs to get the separation needed for a fan. I used a small fan to fit a similar structure early on but the small fans don't seem to have much longevity.
I have one Pi3 in a separate tunnel crunching 4 simullataneous jobs in an ambient temp of 79 degrees. This Pi3's temp oscillates between 60~63C. In another separate tunnel in the same room a Pi2 crunching 4 jobs oscillates between 39-40C.
Don't be afraid of Ubuntu Mate. It is what I am running on all my Piz. Just be sure to get this image for a Pi3: ubuntu-mate-15.10.3-desktop-armhf-raspberry-pi-2.img
Thanks guys. I will probably just add another deck to the stack for the Pi3. The kit comes with a small fan but I doubt it would last long. May just point a 120mm at the stack from the side.
The Pi2, not overclocked, in the stack with no fan run 58C. I ran one Pi2 in that small plastic case and it did fine on temps. Never over 62C. But I figured the Pi3 fully loaded will need some help cooling.
How did you come up with the idea for the PiVE? What was the inspiration?
With all the uses for Pringle cans I am ashamed I could not find one anywhere today. May have to turn in my geek badge. :-(

I like the idea of using the Pi crunchers in a wind tunnel. Like the Pringles can hack. Love the pive look.

Thanks Bikeman!
My Pi 3 is still pending delivery, I haven't considered the antenna placement yet, among other things ;-)
I just ordered that tiny Pi heat sink as well, hoping it will keep the Pi 3 from throttling under full load. If thats not sufficient, I will try
