Rosewill Helium NAS Black ATX Mid Tower Computer Case, Mesh Panel, 4X 140mm PWM Fan, Ideal for DIY NAS, Media Servers, or Small Business Applications

Lots of room for fans, well-designed, easy to assemble (especially for systems needing large heat sink), and good cable management. Manages heat well when burning GPU and CPU at 100%. (For those interested: Put in ASUS ProArt X870E-CREATOR mother board, 2 × 64 GB Crucial Pro DDR5-5600, MSI Ventus 3X FeForce RTX 5090, AMD Ryzen 9 9950X, ASRock PG-1300G PSU, a Noctua NH-D15 chromax.black heatsink, and a Broadcom LSI 9300-8i ). I am not using the case as a NAS server but an AI computer with plenty of room for data. There is room in case for a radiator which I am not using.

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.

Worked out great. Put 10 HDD in this with an old Areca RAID6 controller. Put in a low cost AM4 mobo with a Ryzen 5 5600G (graphics on the CPU) in it and a used 10 GB NIC and works great.If a disk goes bad, I'll be shutting it down to replace the drive - and you can't remove a drive with out pulling a pair all the way out of the case. This is bare-bones but it comes w 4 quiet fans. I added 2 I had lying around. Also - all fans blow into the case so you'll need to turn the one in the back around to get heat out. Case is mostly airholes but it's still sturdy and it takes a really large CPU heat sink since the case is so wide.Met my expectations completely.JG

TLDR : Don't buy this if short on time. Bought the version without "hotswap" bays for a 10 3.5" SAS drive EATX motherboard build. This case cuts corners in function. You do save some money though (in an already niche, hyper inflated) case market - but you do so with the above compromises- Front power panel - basic power, reset, led switches are off a ribbon cable - so you lose flexibility to adapt to any motherboard/be ready to purchase adapters- Form factor is EATX in name only. The internal HDD cage will be almost touching the motherboard edge (missing a couple of mm).- This version case comes with 1 single 14 mm fan. There are 3 sets of metal fan mountings for 14mm fans in front. This could be better done with a couple of rails for the height of the case for all 3 fans..- "Hot swap" cages are at 6Gbps, not 12Gbps SAS transfer speeds (backplane issue)

You definitely get what you pay for and I didn’t pay for much. The case itself is nice, the layout is good and it holds a lot of drives. The airflow is also quite good. However, the metal the case is made of is quite thin and flexes when I put mild pressure on it, the screw holes were often off by a few millimeters for the drive cages, and the finish on the case’s metal scratches off easily.But it can hold 10 hard drives, which is what I needed it for. I wouldn’t recommend it as a personal PC case but it works well if you don’t want to shell out for JBOD enclosures.
