Okay, I have decided to give handwiring a go so I don't have to design a PCB and either run a GB to buy the extras or spend too much just for this.
One thing I really want though is underglow, I have a strip of WS2812Bs, 60 per meter, and I was wondering how many LEDs would be a good amount to use for a fullish size board? The whole case is ~430mm wide and I was debating about getting it printed in PETG to allow it to glow a bit.
I know the LEDs max out at 50mA each, I don't know what the max the Teensy 2.0 and USB ports are willing to give, so that is where I need help.
