Update on the IIAB RPi4 server and Odroid C2 SBC

I am done with the setup of the RPi 4, which will be running Internet-in-a-box (IIAB in short). The downloading of wiki's zim files, all the world maps, and other educational and emergency medical ebooks are completed. The IIAB will be running as a community server if needed during emergencies.
Everything is installed on a 1 Tb msata, I have about 400GB of space left for additional ebooks, videos, and photos, which I will add later.

RPi 4 is booting and running off the 1 TB msata. The UPS battery capacity is about 27,200 mAh

I am adding my old Odroid C2 into the built too. After some fiddling, I had managed to read the battery level and the RTC from 18650 UPS board for the Rpi 4. I am running Ubuntu 20.04 on the Odroid C2. Will do a write up on my installation later.

Here are the photos of the Odroid C2 with the UPS board. Battery capacity is 6,400 mah.

Some work in progress on the case

Had to cut some holes for the 3D printed parts, such as fan mount, power socket and antenna mounts.

For the power socket, I am using a 110VAC / 250 VAC 10A socket with EMI filter.

After installing the 3D printed parts, I applied silicone sealant to prevent water from getting in. The silicone sealant application was kind of shabby.

I am still waiting for the rubber O-rings which I am waiting to install on the cover for the fan and power socket.

I am now deciding on the internal layout of the various other components.

Here are some photos:
