4 + 2 Bay DIY NAS Case, 4 x 2.5″ / 3.5″ Tray + 2 x 2.5″ Internal Bay. MB ITX. PSU Flex. Front USB 3.0 12cm Chassis Fan Hot Swap Backplane. Network Attached Storage Private Cloud Enclosure.

Works well w 10 series intel and rtx 4060 zotac solo fits for an ITX Nas Server Living Room Rig for gaming even. Had minor issue w led diode that company fixed quick

Definitely a tight fit, mine was obviously a repackaged return, it had no screws, the bag the case was supposed to be packed in was not even closed/taped shut, and the biggest clue was the remnants of a previous shipping label and an amazon sticker saying it was a return on the box itself. 1 star knocked off for that. It wasn't "new" and it was missing the drive screws. However.... all is not lost, and I can forgive this considering the case was in perfectly good shape and screws are easy to find if you know where to look.That being said: The case is not bad, it wasn't damaged, and I happen to be a nerd so I had all the screws it needed. I put in a Intel 6600k on a ITX board with 4 sata to the drive bays, and 1 nvme on bottom of the board and 4 more in a PCI-e adapter (Sabrent EC-P3X4 non-bifurcation card) to provide plenty of SSD space as well as hard disk space (22TB, mixed capacity drives) running Unraid. The back fan is definitely loud, the USB 3.0 cable should really have a 90 degree end on it instead of the straight end, as I had difficulty getting the cable seated properly and had to resort to a 90 degree adapter I had on hand in my parts bin. Yay! being a nerd who keeps various parts pays off! The front USB port connectivity works fine with anything I hook to it. It's light, fairly well made but yeah it's not exactly thought out on the height inside because it really was 1/2 mm clearance getting the board in, and I was using an ultra low profile Noctua NH-L9i. That's not easy to get set up at all with that low of a clearance, as well as dealing with an NVMe mounted UNDER the PCB of the board. It took a little shoehorning to get it in while making sure not to dislodge any wire connections.The fan definitely moves a fair amount of air and isn't on the quiet side, but honestly I could care less, fan noise just drowns out tinnitis :) . It's not meant to be a high end NAS, just my "test" Unraid box. This case did just the trick. If you're not afraid to endure just a little nerve wracking to get the board in, it's got plenty of room otherwise.

Update: Lost 2 stars. I went to put in my PCIe 10G card. The "One Full Height Expansion Slot of PCIe" would require the PCIe slot to be about 10mm outside the case. Everything about this case is great, except that they positioned the motherboard in the wrong place---Nice, heavy steel case. I was not disappointed there. The SATA back plane requires 2 4pin MOLEX connectors. Most flex power supplies will have at least that. There is no chassis fan control.There is very little space in this case. Most of the wiring will need to be done before you install the motherboard. Make sure you plug power into the fan splitter before you plug power into the SATA back plane.Downside, and this is big. There isn't enough space on the left side of the case. My motherboard fits until you try to put the cover on. The lower edge of the cover has a U hook on the inside. There is not enough space between the edge of the motherboard and the edge of the case for that hook to fit.My fix will involve an angle grinder. It will work.Their fix would be to move the location of the motherboard about 3mm to the right, away from the PCI side of the board.

Made of good quality materials with a compact design, this case was ideal for my mini NAS/homelab/media all-in-one server build. My only complaint would be the fan noise but its not bad enough to make me want to change it out - and it runs 24/7 in my office about 5ft from where I work. Highly recommended case.

This review is for the 4-hotswap bay version.I was going back and forth between 3 and 4 stars; the number of cuts on my hand from building in this case convinced me to go with 3. It's actually a pretty decent little case if you can abide the limitations.First, the good: it's made with surprisingly thick steel. Even premium cases these days seem to be in a race to the bottom of who can get away with the thinnest material. But when I first took the outer shell off the case to start the build, I was pleasantly surprised at the weight of it!Also, I think it's reasonably well-designed; it makes pretty good use of the little internal space.The hotswap drive trays are pretty decent. Sliding them in and out isn't buttery smooth perfection, but is perfectly acceptable.The actual size of the case is both a pro and a con. I've been building PCs for close to 30 years; the last decade or so has been predominantly mini-ITX based small form-factor (SFF) systems. So I'd like to think I'm comfortable working in cramped cases; I always chuckle to myself when I read reviews of SFF cases that say something like, "if only it was an extra 1cm bigger here and and extra 5mm there, it would be perfect." Isn't that the point of SFF systems? If you start adding "just a little bit" here and there, pretty soon, it's a NSSFF (not-so-small form-factor). Well, here I have to eat a little crow and acknowledge that this particular case needs just a little bit more space!For one, the space between the 120mm chassis fan and hotswap bay is small enough that you'll probably need to use right-angle SATA cables (and forget about upgrading to a thicker 120x38mm fan). I didn't have any right-angle SATA cables on hand, so I just bent straight cables. But it was basically a 90-degree bend, and I certainly didn't feel good about the long-term strain on them. That said, the SATA ports on the cage are stacked close enough better that I'm not sure if right-angle cables would even work (i.e. they might interfere with each other). I hate to say it, but an extra 1 or 2cm of space here would really improve the ergonomics of building in this case.The clearance between the bottom of the hard drive cage and the motherboard is clearly stated in the listing, which is good (and accurate). But it's *very* little clearance, even by SFF case standards. With so little space available, I would be hesitant to use any CPU with a TDP over 15W or so. My build was with an Intel N100, which is a 6W TDP CPU. I used Thermalright's shortest low-profile cooler, the AXP90-X36, and it had only a few mm of clearance. Temps were fine, but this is a very low power, efficient CPU that is easy to cool. (I never got around to stress-testing with e.g. Prime95, so there's still some uncertainty here.)So, it's small, and that's the point. But the biggest problem I had with the small size was that none of the chassis/frame edges were smoothed over. The combination of having very little working space plus countless sharp edges means I ended up with about 10 minor cuts/scrapes on my hands during the build process. I think I have pretty average size hands. But with a case this small, it's inevitable that you'll need to stick your hands inside to plug/unplug something, attach this or that, etc. And in doing so, I found it pretty much impossible to avoid cuts to my hands. These were very minor cuts/scrapes - only a few drops of blood spilled in total - but it's the most abuse I've received in all my history of building PCs!I bought this case to build a NAS system for a friend. My personal NAS uses the similar InWin IW-MS04 NAS chassis (ASIN B0167NCADS). I also wrote a review for that case; I think it's great. By comparison, the InWin is a bit bigger. But with that added size comes a dramatically easier space to work in and what appears to be a decent included power supply. I was trying to save a few bucks with this build for my friend; the cost of this KCMconmey with a *cheap* PSU was less than the InWin with included PSU. That cheap PSU ended up being a dud, and when I went to look for a better PSU, the pricing was such that I decided the InWin was the better value (particularly after factoring in how much easier the InWin is to work in).Another minor complaint is that it didn't come with any rubber feet. I know these are cheap and readily available - but that's all the more reason for the manufacturer to include them!In summary, I think this KCMconmey 4-bay NAS chassis can be good if you absolutely need the small size, are planning to use a very cool-running CPU, don't mind inevitable cuts to your hands while building, and can get a good deal on a PSU. If any of those conditions aren't met, I think the InWin MS04 is a better case and better value.
