I bought a Node 304 for my wife's new SFF computer and I have to say I dislike the case. It's just not up to the quality standards of other Fractal Design cases, such as the Arc Midi I have at work which is a fantastic case.
My two big complaints about the Node 304:
1. The holes are tapped incorrectly in at least half of the places. In some cases, they're not tapped straight. Really sloppy execution here. I've seen other complaints about this on various forums (after my purchase, unfortunately).
2. For whatever reason, the standoffs aren't the right height for the Asus VI Formula board. I ended up using some thin nylon washers to lift up the motherboard high enough so all of the I/O panel connectors could be used. I've not seen anyone else complain about this, so perhaps it's something specific with the Formula's I/O cluster. I disassembled and looked for any possible problems---the board is just too low.
I've never, ever found a case with those problems in my 20 years of PC building until the Node 304. It's just plain sloppy. I got mine on sale at Newegg for $59 with free shipping. Despite that, I'd STILL not have bought it, I dislike it that much.
(As a basis of comparison, my favorite cases have been the Corsair 650D, Antec P182, and Fractal Design Arc Midi.)
