Want to add mini monitor inside my PC for stats and "coolness" factor.

So I have the Thermaltake View 71 case which has the 4 HDD rack in front but right above that there is a big empty space which I would love to use for a 7" or so monitor to keep track of the computer temp, speed, etc and well look cool covering that empty spot.
Just wondering what suggestions you guys have that include the LEAST amount of DIY process as possible.

Bet the raspberry pi folks have some small 5-7” usb powered hdmi stuff
