Helium NAS | ATX Mid Tower Computer Case | Mesh Panel | 4 x 140mm PWM Fans | Supports up to 13 Hard Drives | USB 3.1 Type C | Ideal for DIY NAS, Media Servers, or Small Business Applications

The Rosewill Helium NAS case has been a great fit for my home server build. Out of the box the build quality stood out right away. It feels solid and well put together but is surprisingly light for a steel case, which makes it easier to move around during the build process. Airflow is excellent thanks to the mesh front panel and the four included 140mm PWM fans. Having that many fans included from the start is a nice touch since you do not have to budget for additional cooling right away. Temperatures have stayed in check even with multiple drives spinning and the system under load. The interior layout is clearly designed with NAS and home server use in mind. Drive mounting is straightforward and there is plenty of room to work without fighting cables or cramped corners. Cable management options are reasonable and help keep airflow paths clear. Even my 360 AIO fit with zero drama. I did not run into any quality control issues during the build. Panels lined up properly, screws threaded cleanly, and everything felt finished. That kind of attention to detail makes a real difference when you are spending time inside the case. For anyone planning a DIY NAS, media server, or small business box, this case checks the important boxes without trying to be flashy. Rosewill clearly thought about what matters for this kind of build, and it shows in the final product.

Bought to use as a NAS (network attached storage) server. Already installed several drives and it works pretty well for that. You can place two drives in each drive cage, and there are 5 drive cages. Also room for SSDs on the back side of the case too. The drives need to be screwed into the drive cages, but not a big deal since drives tend to last for years so there is no need to move them around too often. The case looks good and the materials/build are nice quality. Fans are PWM, work quietly and keep the drives below about 32 degrees celsius in an upstairs office. The case has cutouts with mesh dust filter on the top and cutouts for airflow on both sides of the case. Right side of case has cutouts for the hard drives, and left side has cutouts for hard drives as well as motherboard/CPU area. This helps with air flow, but the noise is also not too loud. I have the fans set to a normal fan curve in the BIOS so they ramp up as needed in case CPU heats up. Did overnight burn-in test and temperatures didn’t spike. I wish the back panel had more space for cable storage/management, as after placing several hard drives in the case there are SATA cables and power cables galore that need to be stowed. I had to place the case on its side to lay the right (back) panel on to get it to lock and secure. If I had done a much better job with cable management perhaps that wouldn’t have been as challenging. My most important requirement (drive storage) is satisfied so I will not let it bother me too much. The motherboard I used (Gigabyte ATX) has edge-mounted SATA ports that require SATA cables to be plugged in horizontally, from the right side (terrible design) on the right side of the motherboard, so I have very little room to plug in SATA cables and still route the cables through the cutout to the back of the case (to plug in the drives). Not the case’s fault but just something to be aware of. I had to buy some 90 degree right-angle SATA cables to clean up the cable routing and reduce the stress placed on the SATA port connections on the motherboard. Like every case I’ve ever bought, the instructions that came with this one were very minimal. Took a bit of study to figure out how to remove the drive cages so I could install the drives, but the manual is OK. It would be better if it had more details and instruction. Overall very pleased with this case. The only bummer is it went on sale for $10 less about a week after I bought it! I missed that sale but I do think it’s still worth the price I paid. With everything placed in the case it looks very good, sounds quiet and I am confident it will last for years.

Solid case for a NAS. The fans are not bad for noise overall. The design on the HDD bays are overall good but I was missing a couple screws (had some spares on hand). Overall the space in the case was good and made the set up easy. I'd recommend this case to anyone because you also remove the drive bays to repurpose this as a case for a gaming computer if needed. The only gripe I have is the card slots need to be permanently removed because they are break away. So if you remove a card, you will just have a hole there. A small word of advice. Make sure your remove the break away slot covers from the case before installing the mobo. I ran into a issue with removing them after having the mobo installed because the mobo was covering enough of the card slot to make it harder to remove the break away metal covering it.

After installing my motherboard, drives, and gpu I went to install the PSU and below where it fits in was bent and didn’t allow me to fit it in properly. I was extremely disappointed with that but the idea of this case is great the build quality is just not great. I was going to return it but waited 2-3ish weeks for it and didn’t want to wait longer so I put up with it

One of the few budget nas cases out there for full sized atx. Overall it’s an average case that’s useable but you will quickly note cost savings as you start building. It contains 5 dual drive caddies (4 in main, one in front of psu). They can either support 2x 3.5” drives or 1x 3.5 and 1x 2.5 natively by mounting the 2.5 “upside down” so it’s 4 bottom screw locations align with the holes on the top of the drive caddy. If you use a long power supply, you may want/have to remove the one caddy there as it’s set further back than the others in the main bay (ran into this with an old Corsair axi1500). There are 2 additional 2.5” drive caddies that might be able to fit thicker drives (didn’t check, had room with Samsung 850 sata ssd). These 3.5” dual caddies are interchangeable among their locations so all of them have the tab that sticks out to the side (for securing the psu location to the base of the case). This tab will likely line up with the atx connection on the motherboard and you may have to split apart the bundle, etc. to make it work. While they have various cutouts for airflow, when you install 3.5 drives, they are blocked by the drive. I would think they should have been put in locations to allow air to still pass between two 3.5” drives. If you go with a 2.5 installed upside down on the top and a 3.5 on the bottom, some air should still be able to pass through between the two. If you use a 2.5 to 3.5 adapter, it likely may block that possible air passage. Max gpu length is listed at 280mm I think. An evga rtx 3090 ftw3 ultra (around 300mm) just barely won’t fit and you have to remove 2 drive caddies for cards of that size. It also had a location for vertically mounting a gpu, but I can’t find any reference to it or how long the riser cable might need to be. The slot covers are stamped steel that you have to break out if you want to use the location. They have no way of being re-installed as they aren’t full length. This goes for every slot location. The side panel for the motherboard’s back side is just barely enough for cabling, etc. You likely won’t be able to fit a sas cable with a power supply cable attached to that cable’s drive connector if you install any sas drive in their native locations. You can use a 2.5” drive with a 3.5” drive bay adapter that allows the drive to sit further into the drive caddy (the sabrent ones worked for me). The psu location, while having ventilation on the divider between the main bay and psu, has only 1 alignment option for screw holes. So if your psu doesn’t have both options, you can only install it fan down. The psu mounting location doesn’t appear to be a removable plate, so you can’t flip it that way. Thumbscrews are used in a lot of places (like retaining the drive caddies) but not all of them were in place on my unit and were rattling around inside the case. When I went to install them, some of them don’t line up or feel like they might cross thread. They do provide a bunch of extra screws. The power button on mine feels like it was “pushed in too far on one side” where it doesn’t feel level. It works though. This appears to be the same design as one of be quiet’s cases, but this comes with a usb-c on the top. When reinstalling the side panels you may have to fight with lining their thumbs screws up with the holes on the case. Particularly on the wiring side as you’ll likely be fighting with every wire back there to get it to fit. A few mms of clearance here or at least tabs on the bottom of the panels to help with alignment would have been appreciated. Overall with having to leave out 3 caddies, I can still fit 4x 3.5” sata drives (get 90 degree ones if possible), have space for 2x 2.5” drives, and plenty of space for an evga rtx 3090. If I were using a typical length psu I’d likely keep the caddy installed in that location.

Excellent air cooling and tons (10) of 3.5 drive bays! Fans are quiet even at 100%.

I purchased this case for a NAS upgrade. It’s hard to find a case with ample drive capacity. For the price, it has worked out extremely well. It has ample airflow and the provided fans have kept the temps down. This was a little larger than expected, but is worth it.

Helium Nas - Great case with easy wiring throughout. Typical issue was that the screws were overtightened (especially the bottom HDD bay by the PSU). Fans speeds max around 1500 rpm. Quiet but underpowered for heavy loads and how the bays block the intake. The most significant issue is that this will not fit a 56mm GPU and keep the bottom HDD bay. If they optimized the spacing, they could fit both a 2.5 bay GPU and the bottom HDD bay. Or provide a 1 bay cage accessory. Case would 5 stars if the bottom HDD bay had more mounting points closer to the PSU, better spacing of the HDD bays in general, and bottom HDDs should have opening so you can see the HDD serial numbers (no reason why this space isn't completely open like above).
