First time poster here. I feel the need to echo some of the sentiments above. I've been looking for a decent "no compromises" mini-ITX-case, and was initially very impressed by the Obsidian 250D. It seemed to have the features I was looking for, even if makes a bit more sense for me, convection wise, to tip it on it's side, but that's another story. Nevertheless, it was a bit of a struggle to figure exactly what sort of radiator support the case had, and I was very disappointed to learn that the dual 120 mm radiator support that most reviews and the official sales pitch touts is, practically speaking, untrue. Truth is that the case is built to support the Corsair H100, and practically speaking no other normal radiator. That's a perfectly reasonable thing to do for Corsair, and it might make business sense, but I wish it was made clearer in reviews and the available documentation.
This is a massive let down for me. This could've been such a cool machine and I like the overall layout. I just wish Corsair would have allowed us to do custom liquid cooling loops in the case without trying to make things hard for us. I know that custom loops in small cases are never going to be easy, but that is part of the fun, part of the challenge; this restriction just seems so arbitrary and yet so deliberate. We're talking about allowing for a few more millimetres of room, and that's why it upsets me.
I'm still considering building a 250D; I'm thinking about using 20 mm deep fans, or if it's possible to mod the side of the case slightly, or maybe even going for positive pressure and using no fans on the dual 120 mm radiator. But this has become more of a mental challenge for now, where before I had practically decided to buy the case.
