Was given this little wintel box by a friend fairly recently, but I haven't yet even powered it on. I don't have a power cable for it unfortunately but when I do, what do you think I should do with it? What would you do with it?

I think it could potentially be just a basic lightweight desktop for web browsing and such, maybe a little smart tv box or something like that to replace the Chromecast I'm ashamed to admit I use, maybe run some basic self hosted stuff like pihole or home assistant? Could probably be a little emulation machine for retro games but I doubt it would be capable of much more than that. But I'm not sure there's too many ideas! I need suggestions people
