Hahaha my first couple computers were like that. I didn’t even care about airflow… look how your standard Dell or HP or whatever desktop is wired up.
After I started building for my friends as well, I started caring a lot more about aesthetics. With RGB, all of the fans have two or three wires instead of just one. It’s a nightmare. Now, my fully blacked out computer has only one visible wire—the GPU power connector cables. The massive CPU heatsink blocks off the rest of the already barely visible wires. I’m lucky though, because my case makes it extremely easy to hide them.
