A long journey of "Just one more thing" for the black box

If I must describe this build, I must say its been my very first pc handbuilt.
The pc case has been with me since my college days and I've come to upgrade it several times.
Its a gaming rig built to play some simple games, mmos and adventure games.

Everything I've been upgrading has been but the thought: what could I upgrade or add to this build
I've swapped out the innards once already and swapped out the gpus 2 times.
Made the move from hdds to ssds
Witnessed the of Intel, AMD and NVidia

Honestly enough most of my parts are left overs from each generation of upgrades that I can't even find my pc case and my old hard drives /ssds
Added 2 monitor mounts which made it look like a cockpit of a mech .

I even shucked a 12 TB external hard drive as well and still have a cd drive
Added 3 monitors for each generation of display.
720p to 2k and from 60hz to 165hz too
And even decided to screw around with a projector too. (sadly I went too cheap with the projector I guess)

The thrill of this mess and what each upgrade allowed me was no doubt a long journey of glee and Micro center indulged all my needs.

The next thing I must upgrade is a new pc case... cuz its falling a bit apart.
