I think the best one should be the Dune HD Premier 4K Pro. Larger metal case and venting holes. I just ordered one to replace my regular 4K Plus, because I need bluetooth extended range anyway.
Got my new box. The cooling is indeed better, 30°C idle instead of 35°C for the plastic box.
It’s really heavy, so I guess there’s some big heatsink inside.
I intended to install coreelec using the 2.5" bay drive but so far no luck, only the external USB stick works. The internal SSD in the bay isn’t even visible in Kodi. Any ideas on what I could try to make this work ?
That was fast delivery… 
Sounds like a great box.
Hello, please, when I use an SSD disk, the video buffer does not work, everything works on a USB disk, any ideas?
Thanks. You’ve given me some roads to wander down. Hopefully one leads to the destination

According to what is written there, is it not possible to have a coreelec on an SSD drive in the box? If it is not possible, I would like to know why
Maybe you should start over by mentioning which device you have and exactly what you want to do.
I’m using homatics box r 4k plus when I set up coreelec via USB drive buffering worked when playing movies when I use the same settings but on SSD the buffering doesn’t work
Ok, so now follow the link Portisch posted and get the logs needed for the Team to verify what’s happening.
Thank you for the support, as soon as I get to the box I will do everything necessary. I have never logged here, I hope I can manage everything
If I understand correctly, I turned on logging, reset the device, after booting CE, I turned on the video here, after loading the video should I turn off the logging and send or must the logging continue?
Update: Now I did a clean install on the SSD drive. Version 20.2 video buffer works fine then i tried nightly 21 and video buffer stopped working again t
I’ll just use mine until it burns itself up, if that’s its ultimate fate. I’ve ordered heatsinks and will make a small mod to the box in the hopes the temperature stays cooler. But it works pretty well, so other than the heat, I don’t really have any complaints. I just wish the UI was as nice as Plex’s. Regardless, it gives me HDR10+, which I’ll take over the nicer UI.
Yep, the first thing I did was replace the bottom thermal pad with a larger, slightly thick one so that even through the magnet sits higher than the metal heatsink it now compresses and makes contact with both the magnet and the plate. I also thermally glued a piece of copper busbar I had laying around to the top heatsink.
These mods made no absolutely no difference to the idle temperature, the only difference is it now takes a lot longer to reach those temperatures, owing to the fact there is no ventilation in the box 
My final solution was simply to just leave the top off, my idle temperatures now sit at 50 to 51C
The real problem of this box is the cooldown .Even if you mod it with some passive heatsink ,once it reaches high temps,it’s pretty hard to dissipate the heat in such a closed and tight case.
Personality i modded one of the initial models (Silver color) ,but i went really crazy on it,by cutting down the shied on top of the SoC ,placed a big heatsink (salvaged from old motherboards ) directly on the chips and also connected the heatsink to the aluminum plate from the top cover .
Then i drilled a lots of holes on the bottom and also tweaked a bit the iron plate from the bottom .
After that i did several tests with stress-ng on CE and the temps never went above 60°C after 30 minutes of stress test.
Even so,the cooldown takes a bit and usually will never reach the idle/cold boot temp.
But that’s a heavy mod,not for the faint of heart ,so i can’t recommend it to everyone (let alone the warranty problems ). 
Yep, it’s a shame the makers of these boxes decided money was better spend on a pointless light bar instead of a decent thermal solution

Hello,
B21 does not work in CE In a new installation it is possible to pair and work. You go out to Atv and go back to CE and it no longer pairs in any way. Is there any easy way to solve this? Easy please if there is one.
You need to press pairing buttons again and will start working. Without doing anything in CE.
Dune HD black box
102F (39C) Idle
111-113F (44C) 1 to 2 hours mild usage (no hdr no dv no hd audio)
133-136F (56C) 2 to 3 hours heavy usage
Im using Omega Alpha1 nightly if that matters. (I must say thermals on my Minix boxes are much better).
I have tried it many times. That doesn’t work for me.
