yes , easy to free DIY
In addition to the housing, we also design the adapter board and soft cable, so that wifi7 modules can be put aside to help heat dissipation, plus the power supply is built in. More conducive to commercial products

Good evening @sinovoip, I think my colleague @SpectreDev is right about the antennas. They should be on both the front and back, and on both sides. It’s not a good idea to have all the antennas in one place. Besides, the BE19000 would fit perfectly in that box, since the BE14000 is proving to be a failure in terms of noise and power.
If you truly want to be a benchmark router in Wi-Fi 7, the power supply would have to be external. Creating a heat source inside the box would be a mistake. I don’t think having it inside the box would be commercially helpful.
It would be advisable to reconsider the issue of the antennas and the internal power supply.
Currently, to give Wi-Fi 7 a longer range, since I don’t have 5G modules, I have the antennas placed in this position. The gain has been greater range and I have gained something on the noise issue
Regarding the recommended manual in the assembly video official .
Thank you for listening to your users

That’s excellent news. Will the adapter board be available for purchase separately? And, most importantly, did you check if using the adapter has an impact on the RF noise level?
I have to agree with the others here. You might want to reconsider whether you really should move all the antennas to the rear. You could, for example, provide mounting holes for antenna pigtails on the sides next to the fans, as you have done in the small housing that is already available. In addition, it might not be a bad idea to integrate a USB/FTDI 3V3 adapter and provide a socket for it in the front when designing a spacious housing.
Maybe perforated punchouts or even slottable aluminium 4x antenna holes on each side?
As others have mentioned, a 1U form factor would be great but it could offer a lot of flexibility with that space - with clever screw placement, there could be options of 1, 2 or more mainboards with PSU external or internal. Depending on appetite, daughter boards could be added with capabilities for more PCIe for WiFi, NVMe, SFP, LAN or LTE.
Cooling is also worth consideration - needs thought on where to place fans and heatsinks.
Of course, interference testing is a must for a WiFi product.
This would fit a wide variety of use cases in that form factor.
Good afternoon @sinovoip, it would also be nice if the bottom cover had ventilation holes to accommodate this type of ventilation for routers. I’m sure that for those who aren’t bothered by the noise, the whole banana will be completely cool.
And some holes in the top to let air out. To make it look nicer, we could put a dust cover on top, like those used on magnetic PCs, to hide any ventilation holes that the top would have.
Thanks for listening to your customers and banana users.

1 We will test the effect of antenna position.
2 ,The finished product will have a choice between a built-in and an external power supply

Looks nice but i would put the fans to the corners. Left one to front and other to back corner to get an airflow something like this | / |. Or make it possible to put two on both sides. But to be hones, this are not real facts from my side, just thinking about it cause i made a lot of cooling experiments with the bpi4 default case 
i like the space, could you tell us the dimensions? Cause i would love to put my zigbee and bluetooth usb dongle somehow inside the case The possibility for a dust cover for the fans would also be a special thing i’ve made myself for now
However, looks great, for the antenna positions i am also not sure if this is the best. For me a nicer approach would be to put them on the same side like the ethernet connectors. Or on the side. (maybe at all sides like at the “default” case. you can leave them open if you want some more air or “close” with an empty antenna plug like i did)
greetings
Nice! Maybe add some oled screen in front case?
Now only the indicator board is added, the next version can be considered to add OLED
Better to have small e-ink screen for information like load/temperatures/fan. They can seat on the spi bus with low pin count.

Good morning @sinovoip, are you finally reconsidering having the antennas on all four sides?
By having the BE14 separated, will it reduce noise and increase power?
Currently, these are my temperatures. The highest is the 10GB SFP+RJ45 since I have 10GB symmetrical ports.
On 5GB, my temperature reaches 50 degrees, and on 2.5GB, 40 degrees. With the modifications I currently have, the pink one is the SFP+fiber XGS-PON WAS-110, which is magnificent.
Have you taken the temperatures into account, especially the 10GB SFP+RJ 45?
The rest of the antenna and CPU thermal temperatures.
I hope for your help.
The position of the antenna can be placed on both sides, freely chosen. Our actual test, put on one side has little effect. There will be antenna lines on both sides of the shell spare holes, if not used it, can be used as heat dissipation
Good morning @sinovoip and thank you for your reply.
Thanks for the antennas.
One question: Has moving the BE14 made any difference? Has the noise improved?
Now, as you mentioned in a previous post, we could choose between internal or external power supplies.
Has the UART cable, which has an external output, been taken into account?
Have you considered including the BE1900s in the project again in the future?
And most importantly, when will they be available for sale?
Have a nice day.
1,Power : yes , support the same time.
2,BE19000 design now.
3, we mass production it now . maybe ready in one month.
SFP RJ45 generates a lot of heat, which can only be solved by using a fan or adding a heat sink.
We have reserved a position for 4040 fan
Good morning @sinovoip @simon, I currently have a 35x35x10 fan on both the SFP+ and the RJ-45 ports.
I’m so glad you have the BE19000 design. Let’s see how it works. I know @simon you’re in charge of this project, since I’ve been following you, and when you finish a couple of projects, you’ll probably go back to the BE19000. But if you confirm both, that’s great news.
I’m eagerly awaiting the new case and the BE19000.
Sorry, UART, has it been taken into account to be able to use it externally?
Thanks for listening.
