I'd pass on it unless you absolutely need the power.

PSU's are the biggest weakness of the DC machines, mainly due to cap issues. But they're still pretty good.

And yeah, I fully understand the weakness for dual processor machines. It's just the mental thought of "so much POWER" (no pun intended) that gets me.

That's why I ended up with a Mac Pro that's obsolete instead of something running Yosemite, lol.
