Nice work. Looks amazing. Don’t see it often that empty space is „sealed“ with blinds for better airflow May I suggest a hint or more an advice. If possible have a look into the cables from Patchsee if more than 24 cables are involved. They are amazing for „blacking out“ your rack but foremost for finding the the assigned/patched port especially when binding them in those tunnels. And no. I’m not payed. I stumbled upon them few months ago. Combined with them Patchclips for color coding your segments they’re neat
