I have seen modern fuse panels to replace the old style.

Has anyone made a "Modern" relay board, using todays standard automotive relays and such?

^yep

Also depending on the car you are building or modding you can eliminate it completely, which is what I did. There is an off the shelf cable from Patrick Motorsports to bypass the relay board.
