Black Mini-ITX 4Bay NAS Enclosure Hot Swap 4 Bay with 5.25" Drive Bay Opening

Since details and information on this particular case are sorely lacking, aside from the previous reviewer's very helpful notes, I've attached a bunch of pictures that hopefully give any other potential buyer the info they need.Case features:-Good, solid steel, and as previous reviewer mentioned some case edges are sharp. I installed split braiding on the PSU cables to prevent accidental wire damage.-As also mentioned before, there are no feet - I installed stick on rubber feet to raise the case from the surface.-Drive trays are decent, drive ejection requires you to put a (provided) flat key into a slot in the front of the drive tray.-Front panel connectors include HDD and power LEDs along with power and reset buttons, and a USB 3.0 20-pin front panel cable. Screws are provided for mounting drives to sleds.-3.5" drive cage backplane has 2x molex connectors, along with SFF 8087 (Mini SAS) connector. Per previous review, reverse breakout cable is required if wiring to motherboard SATA ports.-Brackets are provided for mounting a 5.25" accessory. Case does not include 5.25" blanking plate as mentioned by previous review. You'll need to provide your own screws for 5.25" accessories, as mounting depths differ and you're best to use those provided with the accessory. I installed an Icy Dock 8x 2.5" drive accessory.-Maximum CPU cooler height is around 100mm due to the PSU location. I have a Noctua LH-L9i which works ok with my i7-8700 in this case. Another 10mm clearance would have been nice to fit a tower cooler, as this might have helped with cooling the drive cage.Rear Fans:-Provided are 2x 60x60x25mm Evercool F126025BL PWM fans, which run up to a maximum of about 3500RPM and are reasonably quiet.-I found these to be insufficient when all 4x 3.5" bays were populated and under heavy IO load. I had tried replacing these rear fans with Noctuas, but they weren't pushing enough air to keep drive temps down. I ended up installing Evercool F126025BU fans that spin up to ~6500RPM. I sleeved the cables to try and keep the build as neat as possible though I still have work to do there.-I use unRAID which allows me to configure the 3.5" disks to spin down after 15 minutes idle, and have the System Auto Fan plugin configured to ramp the fan speeds at certain drive temp thresholds. This keeps the unit quiet most of the time, but when under heavy load (e.g. parity checks) the fans spin up to their maximum - which is loud, but infrequent enough especially when using Parity Check Tuning plugin to schedule this activity.PSU:-PSU is a 300W unit featuring non-modular 24 pin ATX connector, 4 pin CPU, 3x Molex and 2x SATA power connectors.-The PSU fan is quite loud, and I replaced this with a Noctua 40x40x20mm fan. The replacement was easy enough, but if you feel any hesitation with the prospect of working on an exposed power supply, DO NOT attempt it. Keep in mind it will void the PSU warranty. Noctua fan comes with scotch locks to join the PSU fan plug to a provided 3 pin adapter, but I soldered the fan to the old plug for a cleaner build.All in all, I'm happy with this case given its price point. For the few extra dollars I spent, you can have a really powerful and compact NAS build with a respectable amount of storage.

This is a great Mini-ITX case for a home NAS system with a few minor gotcha's. All you need to add are hard drives, motherboard, CPU, and RAM, and you're all set! I've attached a photo of my configured system which will be helpful since there is NO documentation whatsoever- I believe this case was intended for a manufacturer of NAS systems. Here are my observations:1. There's a 5.25" drive bay. There is no blank or filler- so if you don't have anything that fits in a 5.25" bay you should probably order something- a Blu-Ray drive, tape drive, anything.2. The backplane for the hot-swap hard drives needs a REVERSE SATA->SAS adapter cable. If you just search for "SAS to SATA" or vice versa, you'll get a FORWARD cable, which won't work. The "reverse" cable will give you 4 SATA connectors for your motherboard on one end, and the SAS connector for the backplane on the other end.3. While flipping the power supply up and out of the way in order to install components, you'll need to put some electrical tape on the edge of the case near the output wires. The edge of the case will scrape insulation off of the wires if you're not careful with it.4. There is ONE opening in the back of the case for a pcie card. If you get a motherboard with two slots and you want to use both, you'll need to populate the slot on the edge of the motherboard with a card that does not have any external connectors.5. Cooling capacity remains to be seen, especially with the 4 3.5" hard drives so close to one another. (Perhaps it's a good idea to fill that 5.25" slot with an additional fan?) There are two 60mm fans on the back of the case but I'm not sure if that will be enough to pull cool air in over the hard drives.6. You'll notice four holes in the side of the case under the power supply. These holes are for mounting a 2.5" hard drive or SSD, and the screws are included.7. Quality is so-so. The hard drive trays are really just metal rails with a latching mechanism on the front. They are OK if a hard drive is installed in them. There are no instructions and the power supply is installed in such a way that insulation can be scraped from the wires when you hinge it out of the way. There are no rubber feet or anything on the bottom of the case, it just sits flat on the surface.All in all it was a solidly acceptable deal for me because I needed the 5.25" drive bay and 4 3.5" drive bays.

When I decided to buy this case, I had reviewed several similar cases. This case does not have a well known name brand or fancy styling, but it does have everything you need. It is a small form-factor, but allows for several drives ( 4 or 5 3.5" HDD or 5 or 6 2.5" SSD). The server board is hot swap ready for 3.5" HDD's, but requires 2.5" to 3.5" adaptor trays for SSD's. Also, the case does not include a mini SAS to SATA cable, which is required, especially if you wish to add additional drives. The build quality is very good, the case is made of heavy gauged metal (no plastic) with an included compact power supply of 300 watts. The small size of the case does present problems when installing your PC parts (not much room), and the power supply does require a low profile cpu fan. The air flow of the case is fine for low power cpu's, and the fans supplied with the case work fine and are not excessively loud. The only real critique I have of the case is with the power button, which is of a micro-switch design. It and its integrated HDD lights kept coming loose, I eventually had to remove and adjust to correct. In closing, I have had this case for several months now and it has not presented me with any problems and has performed very well. The price is a little high for a barebones case, but the build quality is good and solid and is build to last.
