K3 4 Bay Mini ITX NAS Case, Hot Swap 3.5"/2.5" SATA Hard Drive Tray, Flex Power Supply Enclosure with 12cm Cooling Fan, 2 USB2.0 for DIY Private Cloud TrueNAS OpenMediaVault

Great Case. I struggled a good bit trying to get everything into position and screwed in, but that's the price of a tight fit. Make sure you have the right components beforehand! I ended up having to swap my power supply to a smaller unit to get everything in. Works perfect for a small media server. My only complaint is the dust accumulation. I've got 2 open disk slots that suck in a good bit of dust. That's to be expected of any PC I guess.

Hay que armarse un poco de paciencia para el ajuste inicial de todas las piezas. Cumple bien su función. Algunos “peros” que identifique: - la tarjeta que conecta hacia los discos hace contacto con el armado metálico de la estructura. Para evitar mal funcionamiento, aislar la parte que hace contacto con cinta Kapton - El ventilador incorporado no es regulable. Si su tarjeta madre tiene conector de 4 pin, va a funcionar siempre a tope de velocidad. Lo cambié por un fan Cooler Master y funciono mejor que el que venia con el producto. - Hay algunas fuentes de poder que cuentan con botón de encendido trasero. Si es el caso, van a tener que modificar con un dremel o alguna herramienta de corte para que la fuente pueda acomodarse.

had to make a small modification to fit some nonstandard parts in, but works really well

Overall I'd consider this case adequate. Once everything is installed it is fine, but getting stuff installed is a pita. The way the motherboard mounts in this case is pretty annoying. I really don't see why they designed it to mount backwards the way they did instead of just moving the mounting posts back and letting it mount like normal. But, because of the way they designed it you have to connect all your wiring on the motherboard before mounting it, and it is very difficult to get the motherboard into place with the posts hitting things and very little room to maneuver. On my particular motherboard that I was using (an ASRock B660M-ITX/AC) the CPU 8 pin power connector interferes with the bottom left post and makes it very difficult to get mounted. Top that off with this being a motherboard with built in wifi and the wifi antenna connectors make it even more difficult. Once you finally get everything installed, pray you don't have to do any maintenance cause you'll have to take the motherboard out again to get to anything. Also of note, the stock CPU cooler doesn't really fit. It will hit the HDD cage. You need something really low profile like the noctua low profile cooler. Beyond the fitment issues, the fan that comes with the case is complete garbage. It is not even a 3 pin fan, wired with just 2 wires and conected to the SATA backplane for power. Meaning it runs at 100% all the time, and it's a noise fan. I swapped it for a Noctua that I connected to the motherboard. If you get a Flex PSU with a toggle switch you will also have to cut a notch out on the case because it does not have an opening that allows for that. Otherwise, my final complaint about the case is just that it has sharp edges in a lot of places. That combined with the tiny amount of space to work in means cutting and scraping up your fingers / hands while working in this case is inevitable. On the good side though, it is a nice compact case for a 4 bay nas build. The hdd trays aren't terrible. The outside of the case looks good and doesn't feel like low quality.

Threw in a small ITX board and filled it with disks. Add a PSU and off you go. Fan is quiet when running. Loudest part is the disks - may add some soundproofing since heat isn't an issue. Lights on the front are bright as heck. Just an FYI if that bothers you. I like it so I can see its on/working from across the room. Simple case is easy to work with and the drive trays work smooth too. No sharp edges and no complicated parts or fittings.
