Hello all :)

I'm making a custom PC in an old console (Atari 2600), and am struggling on how to make neat and clean looking ports for the HDMI, USB, and Ethernet wires to connect to. I think if I just cut holes in the console and stick the wires into them, it will look pretty ugly.

Here's what I want to avoid:

Here's what I want to emulate:

Is there a place to buy those "port borders" in the second link. I have no idea even what to call them.

Thanks!
