Just wondering if anyone is using this Magma Expansion chassis with DaVinci and if it's working out for them.

I already have the Cubix Desktop Xpander, but want something rack mounted. Cubix is releasing a new one soon, but it's double the price of this one... Is the Magma worth it or should I hold out for the new Cubix?
