    My new favorite Case built

    Love at 1st sight, I know it sound cheesy, but it's the truth. I couldn't wait to get my hand on this and upgrade my computer. I used to have the H1, and it was one of my favorite builds—until the H2 came out. Now, this is my new favorite.

    At first glance, the case is beautiful, slick, and modern with an update look from the H1. I had to wait to start the built since I order a new GPU and PSU, but as soon it was delivered, I started the built. It had plenty of room in spots and a bit snug in other parts. I still had a blast on the built and using the Kraken Plus 280 on my new built, only complemented it.

    Everything was easy to fallow on the built, the only thing I struggle was on the two spots for the SSD 2.5 slot. They were very closed to each other, so when it came to plugging them with the power and Sata connection it was very challenging. I had to bend the power cable so they can be closer to each other in order to plug them in. Maybe if there space out a bit more, they were very snug to the bottom of the case.

    I enjoy the extra slots for zip tied for cable management, but the Velcro were hard to grab at times, maybe if they had a ring on one side you can loop it and pull to Velcro it together instead of overlapping, other than that I love the case especially split on glass and mesh.

    It's wonderful to know that the case is design to grow with the user in time, meaning I can upgrade it knowing that theirs more room to work with. Way to go NZXT Team.
