Review: Great case, has lock and many lights. - I was able to build the perfect Network Attached Storage (NAS) with this box. I put in a flex power supply, mini itx motherboard with 8 cores, ram, drives, and it is a godsend. Finally 10 Tb of storage in one easy to access case. I just love it, I should have done this long ago. It has lights for power, individual drive light activity as well as individual drive power lights, and several other lights for network activity in general. Very sturdy. It looks sharp in my cabinet and cable management was a breeze. Great price too for what you get! Building your own nas gives you way faster speeds and much more power than buying a prebuilt one. This is the case to buy.
Review: Smallest mITX NAS Case - This is as far as I could find, the absolute smallest mITX NAS case with 4 external 3.5” hot swap bays currently available to buy anywhere. It does have some drawbacks and difficulty building but if you really need a tiny custom NAS over something like a QNAP/Synology then this is the best you will find assuming can’t use something bigger. Building in this case is not easy and was very difficult due to the size so new PC builders should not start with this case in my opinion. A simple but massive improvement to this case design as others have mentioned would be if the drive caddy could be removed by screws as it is currently riveted in. This would make the motherboard install way easier. Even with a CPU cooler that is within spec for height, it still did not want to go in without a fight, I had to bend the case slightly to get it in. Once it is in though, it does have clearance, but cause of that drive caddy actually does not fit natively. Another improvement would be if they cut another air hole in the front panel and added mounts for a second 40 mm fan on the opposite of the one it already supports. This would help add a little bit more airflow and there is room for it, so why not? Lots of cables need to be plugged in prior to installing the board as again the drive caddy is in the way. For my board, this required plugging all of the PSU cables to the board and the front panel connectors ahead of time. The SATA cables needed to be plugged into the rear of the drive caddy first and not the board side as plugging into the back of the drive caddy was quite difficult for how tight it is with that sharp turn. Also be aware that the included SATA cables are shorter than standard which is good for the case since it does not have a lot of room for cable management but depending on where the SATA ports are on your board there could be a length issue, mine just barely reached. I replaced the rear fan with a Noctua one as it’s a lot better than the stock fan however for me at least, I highly recommend removing the rear fan regardless to make the SATA connections easier. You can still squeeze the fan by the cables afterwards. Regarding temperatures as others mentioned the cooling is not amazing here even with my replacement rear fan. One thing that helped for me was setting a custom fan curve and using the PCH as my temp target instead of the CPU as in my case the CPU will likely be a lower temperature than the PCH on average. One last thing since it only supports Flex ATX PSUs, there are a lot of issues with those having very loud fans. If you can handle the steep price, the SilverStone Technology FX600 is the most efficient Flex ATX PSU on the market and if you truly use this system as a NAS, you will never hear it as your load will never be high enough for the PSU fan to need to ramp up. Full load my system is under 100 watts.

## Questions & Answers

**Q: Does the backplane have connections for hdd activity? my motherboard does not have as many headers as there are leds on the case.**
A: no, this not have connections for hdd activity in the backplate, is in the front panel of the case the lights
but comes with the cables for connect to the mobo.

**Q: What cable/connection is needed to power the backplane?**
A: hello i think the cables you need is Molex and come's with the flex power supply.

**Q: Does this case need a motherboard to operate? I intend to use a raspberry pi with this to build a low power consumption NAS. Will it work?**
A: This is a NAS computer case, the only difference from a “normal” computer case is that it includes 4x3.5” removable drive bays with a backplane that the drives plug into. This of a “dumb” backplane that only passes through SATA and power to the drives, there are no logic chips for RAID or anything. So yes, the drives will need to be plugged into a motherboard or RAID card. The case supports motherboards in the ITX form factor.

**Q: Does the backplane support SAS drives if the cables are replaced with SAS cables?**
A: The backplane has no logic hardware, just traces for data and power. Data traces basically function as a dumb cable extension, don’t see why SAS protocol wouldn’t be supported.

### ⭐⭐⭐⭐⭐ Cheap and sufficient
*by S***O on July 5, 2022*

There are a few quirks to this little gem. The SFX power supply needs the small rear support bracket that is included, and it is not easy to install. You need to attach to the power supply first, then the face plate of the power supple (without the screw that goes next to the cord) then attache everything to the case - putting in the last faceplate screw afterward as that screw head interferes with the case if installed first. the included SATA cables are very stiff for the extreme bends they require. length is also a possible issue depending on your board's SATA port locations. There is enough clearance at the top of the case for 2 additional 2.5" sata drives. double sided tape or YOLO will be required. the drive bays accept 3.5" or 2.5" drives. the tray are not Dell or SuperMicro quality, but get the job done. I did have one get stuck, but a little manual persuasion convinced it to comply. the clamshell cover conforms and matches to the chassis reasonable well. There is no hearding cats trying to get all the locking tabs to engage at the same time. temperatures are very manageable - especially for the single fan in the chassis. This fan is not silent, but not overwhelming and removes a decent amount of heat. It does not have great airflow though. The faceplate lock is a joke for security, but holds decent enough for casual deterrent. Overall, the size, layout, and features of this case make it my new go to case for small NAS builds - which I do quite often.
