Yes, I am sure. I owm Megashadow which is wider than True and G.Skill Trident (very tall RAM). 38mm fans are no go (2mm too wide combined setup), 25mm is perfect with plenty of space.

In fact, even if you're going to populate all 6 RAM slots it will still fit, you will just have to mount fans with something else other than those metal brackets. For True any setup should fit with ease, 3, 6 slots, as long as fans are 25mm. Might fit 3 RAM sticks and 38mm fans, but no promises.
No idea, really.
I went with Corsair myself due to the excellent quality and the premium service. My HX1000 has done a great job so far. But your call what to pick. :)
Antec 1200 PSU should be even better if you can afford that.
