A small power bus board with a few options. Has double pads so you can daisy chain if you like - though it should be noted that wiring directly back to the power supplies is more desirable. Fuses can included for the safety conscious, or omitted by simply soldering wire across the pads where the fuse clips would be soldered in. The capacitors are also optional, but can be included to improve power filtering. You can also omit the fuse and capacitor for the 5v rail if your system does not have or need one. 

Build is as easy as it gets, just check for shorts before you plug it in!
