Well, for one thing, I'd go with a beefier and proven power supply. Behringer's doing decent stuff, but you never, EVER want to skimp on power, as that's the part that can cause catastrophic failures. Also, you want to OVERspec the current ratings as far as you can, as this lets the power supply run cooler and, given that heat is the real enemy of electronic components, with a lot more stability. A 4ms Row Power 40 comes out to about twice the Behringer...but has a good amount of more current headroom over it, and in the end will probably be far more reliable as a result.
