I'm flattered to be considered a king of anything lol but graciously accept the compliment

just in from nightshift but short version:
Black paint interior,
remove lower drive cage, adaptors for the 5.25 bay to fit it there or make brackets if you can yourself to fit the hdd's
some drilling behind the mobo tray, inside the boundary of the mobo to facilitate cable hiding

are you keeping the red fan? if so then red themed cathodes may be an option, and as mentioned earlier (are you stalking me?) spotlight leds can draw attention either to something, or away from it, both are handy

I'll get back later with some more ideas though after some sleep,
*Edit 1. another black sata lead, that red ones looking lonely
😛
or all red if thats the colour scheme?
