I am but a single humble meatbag that enjoys games and can’t speak for all gamers, but I generally dislike the typical “gaming rig” aesthetic. I don’t want RGB lights. I don’t like ostentatious looking cases or accessories. I do find it tasteless, to reuse your term.
No sleight on those that do though. If that’s your style, then enjoy it!
The 3b just has USB 2, so even with slow spinning rust, that’s going to be a bottleneck. But it’s probably still plenty fast as a remote storage device for media storage.
Edit: said I didn’t know OP’s use case but in re-reading they did say.
