Speaking of Rpi's IIRC somewhere someone said the the version of BOINC on the Jessie Distro had some issue with one of the projects and it not doing work. If someone remembers can they let us know.

Jessie is the previous release and came with BOINC 7.4.23. The current release is Stretch and it comes will 7.6.33.

There is a later BOINC (7.8.3 currently) in Stretch-backports but the Raspberry Pi foundation don't have a backports repo so you have to use the Debian repo if you want it. I have heard reports that this one may have issues. I have used it on the Pi without any problems. Your mileage might vary...

I recently upgraded my 3 systems (2 * Model 2B and 1 * Model 3B) from Jessie to Stretch and added another Model 3B.
All 4 systems are running Stretch without issues. Hope new work is coming soon ...

Hello Chris

I'm using an open "case" that I got off amazon. It's really just two pieces of acrylic with four brass standoffs and the PI board held in between. The fan is located right above the processor and I have a heat sink installed.

Running seti on all four cores my CPU temp, as reported by the system, is usually around 59C.

As someone else replied, when I said "headless" I meant without keyboard or monitor attached.

Using 5 Raspberry Pi 3s crunching SETI@Home 100% CPU time. I have them in a 3D printed rack and laid on their side with a big 24V fan pushing hair through each slot in the rack and keeping the CPU packet temperature at a nice chilly 38 degrees Celcius.

Works great, currently crunching almost 1500 average credit and am in the top 25% of average credit contributors.

Pictures? :)

Well I don’t know about him but I designed a 3D printed case to hold four side by side with active cooling. I am calling it the Pi ^4 (Pi to the Power of Four) case. I have done another version but am waiting on some parts before I can splash it all over the internet :-)

Pics of the prototype can be found here.
