Right Angle or Straight connectors?
Just as the title asks, would you prefer connectors coming out the side or the top of a circuit board? Assume there is no enclosure right now. Straight up connectors would make every wire come out the top of the board, making it a bit easier to mount. Side connectors would have wires coming out in 4 directions, making it slimmer and prettier, but harder to mount.
