I haven't had the chance to install my system in it yet, but it looks fantastic. It is a beast though, it's very big.
I won it, and I don't normally win things. I guess they don't call them "In-Win" for nothing. It did arrive slightly damaged in transit around one of the feet, and In-Win sent the replacement part out and gave helpful advice immediately, even though I won it. The case I bought from them 6 years ago still looks great as well.
I highly recommend In-Win.

Very nice case but the cable passages are missing especially at the level of the cpu power supply at the top of the motherboard.
