This is probably way better achieved by a $5/mo VPS.

Benefits:

- way faster

- always on (presumably battery backed)

- you're not responsible for disk or hw failures

- better internet (faster, redundant connections)

- cheaper ($60/year vs $100 upfront)

- not fighting architecture differences

- comes with a public v4 address

- usually comes with a v6 address too

Downsides:

- data isn't under your control and is subject to military espionage

- your internet connection to move larger files to/from the remote device may not be great
