Hey. I am looking to add a small panel with a couple of USB ports and maybe a headphone jack to the front of my cabinet. I have seen these on many of your builds. Any idea where I can get something like this? I know many of them are fabricated but there must at least be some sort of USB pass through panel available out on the interwebs. Also, I see that many of you have a little socket ont he back of your machines for the power cord rather than just the power strip cable hanging out the back. What is this called and where can I get one? Thanks in advance for the help!
