The H100i v2 is good.
The Segotep case, not so much IMO.
When it comes to cases, there is a lot more to it than most people think. I'd be glad to go into what the differences in quality are and why one case is a much better choice, and WHY that should matter to you, if you need or would like, but suffice to say that I would try to stay with cases in the mid to higher end range (And I realize prices are insanity on computer hardware in NZ and AU) made by NZXT, Fractal design, Corsair, Phanteks, Rosewill, SOME higher end Cooler Master (Have to be very picky about model on these as they have some really trashy units in addition to a few good ones) or BeQuiet.
Those are the brands that are likely to result in a product that will not warp, does not have cheap sharp case panels and edges inside, has good cable management features that make assembly and cable management much easier to deal with, higher quality components like mini boards on the front panel power and usb panel, and good accurate specifications and support for radiator or air cooler dimensions based on what model you are looking at.
To be blunt, that case is cheap and what you'll have in the end is a cheap case. Cheap doesn't mean good and in the long run, when stuff starts failing, it ends up being cheaper to spend a few bucks more from the start. Don't settle for cheap ass fans and poor build quality. Get yourself something that might last you through several upgrades or complete builds. That case will not make you happy by comparison.
Is that the only site you prefer to order from? I would be glad to help you find something that isn't outrageously expensive but is also a good product.
