I'd be interested in the box design. Would we need two fans to pull and push air out of the box?

Just a heads up.  Do not underestimate the importance of a quality power supply source.

My two Terminus were just working fine for many weeks with the plug packs provided with them.  I was always concerned though that the plug packs were running rather hot.  I had attempted overclocking, however I could not get them to be stable above 200MHz.  Then just last week I noticed they were not hashing away any more.  The devices were constantly being restarted.  Inspired by one of the other members on here, I went and found myself a cheap PC power supply with dual 6pin PCIe power connectors.  The two terminus are now hashing away at 275MHz and look to be very stable, without one restart.

ps.  Also looking forward to the new design Sidehack is working on.

Just my 0.02 cents
My original R808 has been running 24/7 for months now @ 150mhz solid
Reading and following the advice on this board:
Replaced both fans with 50 x 50 x 20 units from Amazon
Both original fans were starting to fail, slowing and chattering but they served their time well up to this point
Original M3 screws were replace with M3 x 50mm. Heatsink was drill & tapped perfectly so replacement was easy
R808 is now running @ 175mhz comfortably
The only downside is louder fans, to be expected tho.
Also changed power supply from the 6A brick to a Corsair Gold PS and using the 6 pin connector
I know it's my imagination but the R808 seems to start faster and run better with the 6 pin connection
Overall, the R808 design was extremely well designed   Cheesy

That's not your imagination; the barrel connector just does not supply enough current. I have a pair that average 107.8 MH/s each @ 250 MHz that have been running for over two months continuously (almost 3 months, now) on a server psu. I could not get above 175 MHz reliably on a wall wart.

I know this is an "old" thread, but I wanted to place a heads up for anyone that gets this far,

You can run the Terminus R808's stable from a barrel connected power brick, just don't by uncertified junk imported from china from Amazon for $10.

We run single R808s at 275Mhz with 0 HW or heat issues off good quality power bricks(yes we sell them) and for larger scale multi unit mining, you can also get a GekkoScience Power Breakoutboard kit and a HP Universal power supply for around $100, if you cant find a good "PC Tower" power supply that fits your needs.

Cool, thanks. I've been looking for a HP power supply. @jstefanop announced a scrypt miner so maybe I can run my Terminus R808 and Apollo on the same power supply! Wink

these do look kinda awsome, Ive been tinkering with a raspberry pi/R808 combination that would work the same way. I dont want to produce the new 3d printed case though till I get ahold of the new model from sidehack

I had figured on putting the new one in a case at the factory.

Ya, i figured I could make something that would "snap" on the side of your case.

So it looks like one of the fans of a pod is giving up the ghost on me.  It was one I had pre-ordered way back when.  I figured I'd ask, where might be the best place to source a replacement fan?  They're what, something like 4.5 CM square?

5cm. Somewhere back a few pages someone put up an Amazon link to a taller fan that fits and reportedly does a better job cooling. Might also have to track down longer screws.
