The heat syncs that poppageek employs on his his stack seen here seem ideal. You want as much exposed surface area as possible and that can only be achieved vertically. His syncs are tall and offer the most surface area. Also they are copper (right??). The ones in the Adafruit video are short and offer minimum surface exposure. In the video, there was no air flow over the heat syncs so that makes a large difference. I looked on Ebay for the type of sync poppageek is using but could only find them with a fan which I would not require.
I had 1 set of them left (purchased originally for the Pi2's) that I used. The SoC heatsink is 13x13x13mm in size. On a Pi2 that was enough to keep them cool, but the Pi3 needs airflow and decent size heatsink. A fan is a mandatory piece of equipment.
I have contacted 2 eBay sellers. One was selling the two heatsinks and fan as a kit. The one with the kit hasn't responded (I wanted the heatsinks without fan). The other one I purchased from before doesn't appear to have any stock at the moment. There was a seller on Amazon but they too appear to be out of stock.
I wouldn't suggest using the flatter copper heatsink as they just don't provide enough surface area to help. I am surprised nobody has come up with a proper PC like heatsink/fan combo for them yet. Noctua have a C shaped PC cooler which would be ideal if they could shrink it.
I found a Raspian img date 2016-2-26 on my Windows machine so loaded it and it did fine. Then ATT got internet and TV working once again so downloaded Ubuntu Mate. Pleasantly surprised at how snappy and responsive Pi 3 is. Even running Firefox. I am a very impatient person so if I say it is responsive it ain't bad. ;-)
The heat sinks I have on the Pi 2s are Enzotech BMR-C1 for GPU memory. Got them when I changed the fan/heatsink on a GPU a few years ago. They are forged copper.
While the Pi 3 has been fine in a small clear case without fan so far I have not installed Boinc either. May tomorrow, have company coming so may not.
Do not know what I am going to do yet as far as cooling/case/fan for crunching. Would like to try something like what Bikeman did. A Planters peanut cardboard can might work. :-)
BTW- Bikeman, if you do not mind what do you do with your older Pis? Other than keep an eye on felines that is. ;-) I am using a 700mz 512meg Pi as a pi-hole. Works great. Better than the pi-hole web site anyway.... https://pi-hole.net/

Ah let's see:
Media Center : OSMC with Kodi 16.x (mostly for audio: internet radio, music collection etc) : Pi 1 at 850 Mhz . Yeah this one should be upgraded to a a Pi2 or 3, but so far the Pi 1 is fast enough.
Webserver : using lighttp Pi 1B
Local samba file server, git server, etc : Pi 1B
A bit of home automation: controlling some lights via 433Mhz transmitter that switches off-the-shelf remote controlled power sockets (RaspiConnect app, rc_switch library). Temperature and humidity sensing with cheap DHT22 sensors. Motion tracking with super-cheap HC-SR501 PIR sensors. IR illumination for night vision with "NoIR" variant of raspi cam. (Pi 1B and 1A)
Also trying to build a seismograph from a toy laser interferometer, not successful so far, but nice as a demonstrating tool for laser interferometers. Pi 1B for switching the laser via a relay, signal recoding via photo-transistor and USB sound card, signal processing and visualisation via sox.
The hi res moon video is quite amazing. I also liked the captured meteor images on the website. So what telescope are you using for the moon imaging? And you must live where there is low ambient light.

The moon thing was done with a 6 inch (150 mm) Newtonian telescope, f=750mm , so f/5 .
This is not ideal, for this kind of moon imaging you would want longer focal length, but it's the only bigger telescope I've got at home:-). The moon is so incredibly bright (compared to stars (other than the sun ;-) )) that light pollution doesn't really matter that much, what's limiting is the "Astroniomical seeing" https://en.wikipedia.org/wiki/Astronomical_seeing which depends more on weather (and site elevation) than anything else. So you can do pretty good hi res moon images even from urban or sub-urban sites actually.

Poppageek, I've been getting the same error. I'm unable to load anything for Einstein though the BOINC client manager. I was about to head to a coffee shop to spend the couple hours or so trying to figure out how to get it running properly on my Pi3.
I'll let you know how it goes. Vice Versa please if you figure it out too. :)

Sure will Adam. Still trying. I have 2 other Pis, all with same Raspian, updated, same Boinc version and no problems at all with them.Turned on debugging for hhtp and file_xfer in cc_config and still nothing that helps.
