Rosewill Viper Z Mid-Tower ATX Case Review

Rosewill Logo

Rosewill, which is owned by online computer parts reseller Newegg, was established in 2004 as a manufacturer of computer components such as power supply units, cases and cables.  Rosewill boasts that they currently manufacture over 1,400 different products in various categories.  One perceived issue by enthusiasts is that due to the wide scope of their product offerings, Rosewill doesn’t have focus on just enthusiast products and isn’t catering to or relying purely on support from the enthusiast community.  While Rosewill products are not typically a first choice among enthusiasts, the company has been making pushes towards the enthusiast market by producing relevant products, such as their  RK-9000V2 keyboard, which offers Cherry MX switches, in addition to sponsoring various e-sports competitions.

I haven’t had any personal experience with Rosewill products to draw from, so I am looking forward to reviewing the Viper Z, a modern styled mid-tower ATX case with a pretty extensive feature set for $51.99 shipped after rebate and a promotional discount.  The ATX case market is extremely competitive right now, so Rosewill will have to truly make an impression with their Viper Z for it to be considered a viable contender.  With Rosewill tagging the Viper Z as a “ferocious warfare machine” and then including a windowed side panel and blue LED fans, this is obviously a case targeted towards PC gaming enthusiasts.  Let’s take a look at the specifications for the Viper Z and see if there’s anything of note.

I was unable to find some key information when going over the specification sheet for the Viper Z, such as the maximum supported CPU cooler height and the maximum PSU length supported.  I researched further and found that using extended PSU’s and taller CPU coolers such as the Noctua NH-D15 are supported, but I feel that this information should be readily available, as it can affect buying decisions and most case manufacturers provide this information in their specifications.  Unlike most Mid-Tower ATX cases which offer just seven, the Viper Z offers eight PCI-E expansion slots, with a supplemental slot that sits above the other slots also available.  Overall, the specified component support offered by the Viper Z is more than adequate for a Mid-Tower ATX case and I definitely liked seeing that an integrated card reader and fan controller are included, as these are typically premium options seen on more expensive cases.

Rosewill currently offers one model of the Viper Z.  The Viper Z is currently available at Newegg for $51.99 shipped, putting it in very competitive territory.  Since Newegg is the primary distributor and reseller of Rosewill components, I’d expect to consistently find the best price on the case here, though it won’t hurt to check other marketplaces before your purchase to find the best possible deal.


Rosewill’s packaging for the Viper Z is basic and doesn’t offer any information beyond the weight specifications and model information, which is fine given that this case will mostly end up being purchased from online resellers and not in a brick and mortar environment.  There is a line drawn graphic of the case front side profile and another smaller drawing illustrating the top fan area.  The box arrived to us unscathed from Rosewill’s City of Industry, California location after being shipped there from their New Jersey warehouse.


Opening the box reveals the case packed in a plastic bag and sandwiched between white Styrofoam inserts.  This is very typical case packaging and proved more than adequate, as our case arrived to us unscathed.


The accessory bundle included with the Viper Z is barely adequate and a bit sparse.  There are five zip ties, which is adequate, though more are always appreciated.  The screws are all packaged in one bag, which is a practice I simply don’t approve of.  For experienced builders, including all of the screws in one bag isn’t an issue, but for a first timer it would prove extremely helpful to have individually labeled bags.  The manual included with the Viper Z is basic and has information on how to remove the panels to install fans and other installation guides.


Rosewill included a case speaker with the Viper Z.  A lot of motherboards don’t even include a provision to attach this speaker anymore, but it certainly is a welcome addition. I’m reminded of my old 286 and 386 systems that played all of their sound through the speaker integrated into the case.

The Rosewill Viper Z carries a one year warranty against defects in workmanship.  In case you’re wondering, case warranties typically get applied towards faulty IO panels or ports and can come in very handy should you have a USB port fail, or if the integrated card reader should stop working.  A one year warranty is pretty weak, considering most case manufacturers offer multi-year warranties on cases.  Also, based on my experience, cases end up being an item that doesn’t end up getting shipped back for warranty support, so case manufacturers can typically afford 3-Year warranties, since they’ll just be replacing small, modular parts, if anything. I haven’t had any experience with Rosewill support to draw from, so I can’t comment on how their service works or how warranty repairs or part requests are handled.  If anybody has experience with Rosewill support, please let us know in the comments.

    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.

        • meddah4

          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.

        • John Ashley

          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.
