Review: Interesting Build Small NAS - The case is small and the video build is misleading. I used a 1155 itx MB and i5-3470 cpu with a Thermalight AX90 cpu cooler (35mm). However, the MB cannot be installed without removing the HDD tray. To remove the HDD tray the front cover needs to be removed (4 screws and 4 tabs). Then remove 4 screws from the back and 4 screws from front and the HDD tray can be slid out the front exposing the MB mounts. There is about 1mm gap from top of cpu cooler and bottom of HDD tray when reinstalled. If noise is an issue, replace the 80mm fan with quieter fan. As mentioned in other reviews, there is little airflow, but temps seem ok at stock settings. Other than a challenging build, the case is great. Have fun with it.
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.

### ⭐⭐⭐⭐⭐ Great little case
*by T***E on January 18, 2024*

Paired this with an ASRock J4125B-ITX motherboard and a 4x port sata card for a NAS build. The stock cooling fan definitely makes it sound like a server, but it has good airflow. Plenty of room inside for routing cables and has an interior mount for a 2.5" drive in addition to the four bays. The feet on mine felt a little cheap and were loose. The case is pretty attractive with the front mesh showing status LEDs for the motherboard and four drive bays. The LEDs are fairly bright if the room is dark, but shouldn't pose an issue if trying to sleep in the same room as the case fan noise will probably keep you up.
