i7 (mobile processor) with the built in Intel gpu. 16G ram. 120G ssd. It's an optiplex. They're pretty cheap on Amazon / ebay as refurbs. I bought it for the processor. Bought and upgraded the ram and ssd separately. I just have kodi on it (on Linux Mint). Everything is stored on my synology, which has an m.2 ssd cache. My TV is only 2k, so I haven't tried pushing any higher res stuff. I was surprised a few years ago when I started playing h.265 videos. No issues playing it at all. I didn't upgrade the ssd at first, but noticed the box got pretty hot by the end of a movie. That upgrade dropped the temp in the box a good bit. I don't think I'm pushing it much. It just gets warm a little and utilization remains under 50%. The box is really snappy too.
