I have a G19. That customizable LCD is nice.
Too bad it's a rubberdome, and no mechanical keyboard has an equivalent software-controlled LCD...
yet. That's what this thread is for.
There are a couple other things I want to do with it, while I'm at it, such as not needing an extwrnal power brick. I'm debating between a power jack somehow sticking out of the case (perhaps adding in a jack connected to a molex?) or making a USB adapter.
