Rosewill Viper Z Mid-Tower ATX Case Review

Jump To:

Rosewill Viper Z Mid-Tower ATX Case Build

Motherboard: MSI H97 PC Mate
Processor G3258
CPU Cooler Thermaltake Frio Silent 14
System Components 1x 2.5″ OCZ Vertex 480A 240GB, 2x 500GB 3.5″ Seagate, 1x Plextor DVD-RW
Power Supply Corsair RM650


Installation into the Rosewill Viper Z was very simple.  I started by installing a Corsair RM650 power supply unit, which screws into the rear of the case.  Installation of the PSU went smoothly and it was actually satisfying strapping it into the case.


This is the strap that holds the power supply into the case.  I don’t think this strap will come in handy, except in extremely rare circumstances, but it’s not in the way or causing any inconvenience.  Strapping the PSU down within the case is actually a refreshing experience, as you know your PSU is extra secure.


Thanks to Rosewill installing the standoffs for the motherboard, I didn’t have to do anything to prep the system for the motherboard besides install the IO shield, which snapped into place without issue.  There was plenty of clearance for the Thermaltake Frio 14 heatsink to be installed.  Taller units like the Noctua NH-D15 shouldn’t have any issues installing in the Viper Z.


Thanks to the well thought out cable cutouts and routing paths, I was able to route the USB and audio headers to the board in a very clean manner.  Front panel headers were also very cleanly labeled and laid out, with a nice slit beneath the board present to optimize cable management of these headers.


The rear of the case cleans up pretty well, despite there only being a couple of zip ties included to aid with cable management.  I had no problem closing the side panel.  Thanks to the ample cable ties and rubber grommets for cable management, the Viper Z was an absolute pleasure to work with and building the system was a very simple affair.


Here, we can see an unfortunate situation presented by the Viper Z.  The side panel closes very close to where cables insert into SSD drives and the side panel can push against the power and SATA cable, possibly.  This is an oversight and something end users will need to be aware of in order to avoid possible damage to their drive.  We didn’t note any issues with our configuration, but users without flat cables should definitely be weary.


Besides our issue with the way SSD’s sit too far back in the caddies, I didn’t have any problems with building into the Rosewill Viper Z.  The cable management in the case is well thought out and there is adequate cable tie down points on the rear motherboard tray.  The Viper Z would be a great case for a first time builder, as it offers a straightforward, spacious internal design with minimal frills, along with solid build quality.  I was able to build the test system into the Viper Z and do adequate cable management within an hours span.

    I like the single SSD/HDD tray. Minimizes distractions from the air flow coming in the front of the case. I’d rather run my back up(s) HDD in an external unit configuration. Nice case. Viper’s on my future buy list.

    Just built my Ryzen 5 1600, gtx1080 build in this. Worked very well. Taking the optical drive bay out was a hassle. Wish there was official support for a third fan on the front (I just zip tied the 3rd fan where the optical drive bay used to be).
    Air flow is great, my CPU is running at 30 at idle, case is fairly quiet.

    Overall great case.

      Is that top i/o panel (off /on) easily removable, accessible for rewiring?

      • John Ashley

        While I have not tried to remove the front I/O panel, I do know that it is difficult to get in and around it. I would imagine you could remove the front I/O if you wanted.

          I really like what I seen of this case. I want to replace a Corsair Carbide 330r case that has some features like it but turned out to be a bad buy. The motherboard mounting holes didn’t align with the Asus board properly. When I modified the case to fit it, it put a lot of stress on the gpu PCIe slot and card. I ended up burning thru 2 video cards before I gave up on it. The rear 90mm exhaust fan pinched the rear i/o panel -ended up outside the case, too. Along with fragile plastic hinges on the front and snap-on tabs that bend on the top cover, really made for nightmare of the year.
          I’m really considering Rosewill case and I hope it serves you well.

          My MSI Tomahawk B350 board fit perfectly in this case. I had not alignment issues.
          My biggest complaint was the sharp edges. While not terrible, I did walk away with a few nicks. So watch the corners.
          One of my biggest positives for this case was the height of the stands on the bottom. My case sits on carpet by my desk. There is about 1.5″ clearance between the carpet and the intake for the PSU.

          I just put my order in at Newegg. I almost bought a Fractal Design 4 but wasn’t persuaded by it’s features as the Viper did. Watched a few Youtube videos which helped encouraged me. Thanks for the big tip. Looking forward to seeing it on my door step.

        The top IO isn’t easily removable on the Rosewill case. It is a very easy case to build into and work with, though.

        • meddah4

          They say that the on/off button easily breaks and falls in. I was hoping to reinforce it or make a new button. Yeah, I like the features it has. tall feet, single hdd rack, space for 2/140mm fans in front and a 240mm liquid cooler on top. I’ve put my Vega card back into the box until I can get a water block for it. It runs very hot. 84c+.

  • nice article

  • A very nice looking case for a decent gaming PC

  • Nice review. Appreciate your hard work in arranging all the stuffs

  • Nice case and good review. But maybe you should have put more images of that case.

  • Billy Dark0

    Great review! Thank you for taking the time to look at it so thoroughly and provide pictures.
    I do have one question about this case. I did read that a 240mm radiator was supported. Would you say that just about any 240mm AIO liquid cpu cooler would fit? With it being a mid-tower, and judging by the pictures, it seems it would be a tight fit on top.
    More specifically, the Corsair H100i GTX (240mm) as the AIO cooler.
    Thanks again! Great read.

    • Sean Kumar Sinha

      The H100I GTX will fit just fine but you need to run the fans on top. It won’t fit with the H100I GTX and fans installed within the case, the fans will have to sit in pull mode above the radiator in the dedicated fan chamber, while the H100I GTX sits in the main case (See my MasterCase 5 review for an example of this). This actually works quite well, as the fans are able to draw out warm air and it minimizes dust build up.

      • Billy Dark0

        I checked your other review out and I see what you’re saying. Thank you very much for your help!

        • Sean Kumar Sinha

          The way the case is setup makes radiator installation easier because the fans can sit in their location and then you only have to line up the radiator, rather than hold the radiator and fans in place while screwing them in. Let me know if you end up getting a Viper Z. It’s a great value for the money and I was pleasantly surprised at how good it is.
