Yeah I agree not seeing anything but the display makes it look good, it's also quite stable when pressing on it. If a weight was put in it wouldn't move when using it. The power goes though the RJ45 that's plugged in the pictures, the other jack isn't required, only useful if you program the updates away from your computer, then you have a way to power it up as the USB doesn't have enough current for the display. These buzzers are quite loud, turned up I can hear it in my bedroom with the box sealed up. You won't be able to run that big of a speaker unless you added a small amp. If you try something bigger make sure its compatible with a digital signal. I don't know how that works.
