In my living room I have a uITX cube who’s sole purpose is to run RetroArch and Kodi. It’s hooked up to a 60" 4k TV and 5.1 sound system. Currently it has a water cooled intel i5-4690k, 16Gb DDR 3 and a 4Gb nvidia GTX 960 graphics card. It’s not overclocked but the water cooling runs quieter than air cooling.
I’ve been thinking about upgrading the CPU/Mb/RAM but since I’m not using the onboard graphics is there anything around that’s significantly better?
