If you're just looking for power, something like the TipTop uZeus or the endorphines 2hp power are great for small cases. for the modules you listed, they draw a little over 500mA on the +12v rail and less than 100mA on the -12v rail. With the right wall wart or power brick, uZeus will pump out 2 amps +12v and 500mA -12v, and the 2hp Power produces 1amp +12v and 700mA -12v. Either would give you headroom to add one or two more modules. Cheers!
