Things still to do:
1. Fit some rockwool behind the speakers to improve the sound
2. Replace 1080p monitor with a 4k monitor (I've used DSR to see whether I'm likely to be able to run the games I'm interested in at 4K @ 60fps)
3. Rebuild the back
4. Fit some LED lighting as it sets the mood when I have the lights off
5. Design some alternative artwork toppers (laminated) so I can swap them out periodically (new Mortal Kombat X, Street Fighter V, Tekken 7, Injustice 2, generic etc)
... well, I started on the LED lighting. I'll be adding a dimmer tomorrow as it'll arrive then. I will also be fitting some to the back.
