The awesome-selfhosted list is ..well.. awesome, however it lacks a hardware category to collect links and information on cheap low power small devices to be used to host our personal data/services, both to avoid keeping beefier PCs up 24/7 and to better isolate their functions.

It could for example include from tiny boards with the bare minimum necessary to host very light services (Single NIC Raspberry/Orange/Nano/Banana PI, etc.) to small sized boards either with storage capabilities or a couple NICs to be used as moderate traffic firewalls (PCEngines.ch APU, etc) and bigger and more powerful systems with multiple NICs for SOHO+ sized servers and firewalls (www.ipu-system.de etc).

Also, this m.2 to SATA port replicator reportedly works perfectly with Linux (Possibly FreeBSD/XigmaNAS too) as do many other JMB575 based cards. Could turn any cheap board into a low cost NAS. https://www.ebay.com/itm/203735847811

Too long for Mini PCs accepting only 2242 modules? Here's the extender. https://www.ebay.com/itm/263570657382
