Unless dimming these is of utmost importance to you (for a fuge I would think not) I would get either a meanwell LPC-35-700 or a LPC-60-1050 (if you want higer mA). This way you just wire it and go...if you need to add more LED's you can (up to 12). The buckpuck costs the same, but you still need to buy all the extras to make it run and it caps out at 6 LED's.
Just my humble opion though. Here's a link where you could get the Drivers.
