@jalcine hope they have a v4 update for that enclosure soon, but if they don't I'd probably print one anyways!
I have that touchscreen with the previous Pi3. It makes a very nice LibreElec/Kodi interface, but the extra power of the Pi4 would be super useful (hardware h.265 decode!) and the better I/O would make it a suitable media server not just a front end.
I'd use it for #HomeAutomation to do real smart home stuff like #mycroft instead of creepy spyware smart home like Amazon or Google.
