Auxillary Fuse Block

Not sure auxillary fuse block is the correct description for what I am looking for. I am going to be using an electric fuel pump, Electric fan, and headlight kit at some point. Was wondering what you have done for a central fuse box out under the hood or under the dash. Any pics of it and where did you get it from. I really dont want to load extra draw on the old original box.
Thanks
