i only have experience with raspiblitz on raspberry pi, which has worked out okay for me so far, but recent strain on lightning network (ordinals etc) has really put raspberry pi to test, especially if you want to run anything interesting in terms of apps, so for hardware probably makes sense to run on old laptop as k3tan suggests (see stephan livera podcast from maybe 3 months ago) or intel nuc etc as dimi suggests below (just realizing now that dimi avatar is just dimi being dimi; had previously thought he was telling me off everytime he reacted to a post. :)
