Does anyone know of a similar product? I'm particularly impressed by the built in UPS and five bay storage.

Yeah that's a great idea for saving space and would be perfect if it automatically shut down after the battery gets low

Doesn't exist AFAIK unless something new was announced in the last couple of months that I missed - I researched quite a lot a little bit back. Somewhat similar scopes but without both of those: https://wiretrustee.com/raspberrypi-cm4-sata-board/ https://wiretrustee.com/raspberrypi-cm4-sata-board/ (not launched yet) https://shop.allnetchina.cn/collections/sata-hat/products/penta-sata-hat-for-rock-pi-4 https://shop.allnetchina.cn/collections/sata-hat/products/pe... (they also have an enclosure kit) https://www.hardkernel.com/shop/odroid-hc4/ https://www.hardkernel.com/shop/odroid-hc4/ (just 2 drives; I have one as a sink for automated ZFS snapshots using zrepl; a friend is using one for syncthing+apple time machine sink) If you want something within the coming ~2 years and any of the above don't fit your bill I think you'll have to resort to x86 and an external UPS. I'd love to be proven wrong, though.

I have a somewhat similar project based around the raspberry pi. It's rather DIY compared to Helios64's project - 3d printed case, hand soldered electronics, amazon sourcing - though the goals are similar. Specifically, my goals were to host 2x 3.5" drives and to be printable on a standard 200x200 mm 3d printer. https://old.reddit.com/r/DataHoarder/comments/n277ip/raspberry_pi_baby_nas_project/ https://old.reddit.com/r/DataHoarder/comments/n277ip/raspber...

I've built a couple NAS machines off Atom Mini-ITX boards, and in one case I supplied the mainboard and the two disks using a PicoPSU 12V adapter. Once the system accepts 12V, the UPS can be a car/motorcycle battery left inline as buffer, so that in case of blackout there's no switching involved. Not compact as the Helios64 UPS, but it works and is less risky than having two Lithium cells near the drives. I didn't try this configuration as my PicoPSU needed quite accurate 12V input, which the car batteries would exceed when fully charged, but their M3-ATX Automotive model accepts from 6 to 24 volts making ideal, as the name implies, for being supplied by a car battery. Regarding the 5 bay storage, you can buy backplanes with pull out bays for 5*3.5 disks that would fit into 3*5.25 bays. A search for "3 to 5 sata backplane" returns some products.
