most computers will run on it fine. raspbery pi were to go to a few years back, inexpensive, low power usage and decenttly powerful; however, the shortages during covid meant that they were very expensive, and on those price ranges, mini computers blew them out of the water in terms of performance. Look for a pc with n100 (which is still way more power than you need) and you should be good.
tldr: any computer in the last 10 years will run it fine
the AOOSTAR R1 2 Bay 40T would be a better buy than ODROID H3+. The n100 is faster:

It would be a sleeker package than an odroid and cheaper
