K7 8 Bay NAS Case, Computer Enclosures Compatible Micro-ATX Mini-ITX Motherboard, 3 x Fans, 8 x 2.5/3.5" Tray, Network Attached Storage Server for Home(Diskless)

This is a great case and not just "for the price." There's a lot to like here. The case takes both mATX and Mini-ITX motherboards.The drive trays can be a bit finicky to get clipped into place, but what plastic drives trays aren't, and how often are you really going to be removing/adding hard drives? Don't force the tray in and you won't break anything. The drive trays have mounting holes for both 3.5" and 2.5" drives. Drive trays have a blue light for power and a green light for activity.The 2-compartment design keeps the heat from the hard drives from washing over your motherboard and ensures the air pulled over the drives has a straight shot out of the case. I have 8, 7200-rpm drives and after 48 straight hours of file copying, temps were all b/t 47C and 51C. They idle at around 44C. Those are not bad temps at all for eight, 7200-prm disks crammed together in a quiet case.The fans the case comes with are not horrible. They are completely acceptable for stock fans. In fact, I bought 80mm Noctua Redux and 60mm Redux fans to replace all of them. The stock 80mms are actually not as noisy. The Redux fans have a bit of a high-pitched whine to them, which is more annoying to me than the hum of the stock fans. The 60mm Noctua is quieter and moves the same air as the stock 60mm fan, so that got swapped out.Due to the small upper compartment, and the good exhaust ventilation design, a single, quiet 60mm fan is sufficient to keep the CPU reasonably cool. If you don't mind fan noise, put a high-speed fan in there and you could keep a higher-wattage CPU fairly cool.I have a SuperMicro A2SDi-8C+ motherboard (Atom C3758 CPU) in this case and the CPU idles at 45C and never breaks 50C even under load. That's with the tiny 40mm fan that comes stock on the MB CPU HSF. You could fit approximately a 1U-height or other low-profile CPU HSF in here, so you might be able to keep a more powerful CPU reasonably cool (but noisy). I wouldn't put a 150W+ CPU in this case though.The case is SUPER-EASY to build in. The PSU (Flex format) lives in the lower compartment, so there's nothing in the MB area but the 60mm fan.There are some small gotchas that you need to be aware of. Most Flex PSUs don't have really long cables. You will need an ATX 24-pin, and CPU 12v 8-pin extension cables b/c most ATX/12V MB sockets are the side of the MB opposite of where the PSU mounts in the bottom compartment. I'd like to see these extensions included with the case, even if they upped the price by $10. It's likely that 90%+ of users will need these extensions and it can be a real bummer finishing up your new build only to realize you have to wait another few days for the cables you didn't know you needed to arrive b/c your PSU cables are 2" too short.There are no SSD mounting locations in the MB tray, but there is space along the sides of the compartment to mount SSDs with double-sided tape, which is what I have done. It's not likely you'll be moving this case around, so double-sided tape on SSDs that weigh like 1 ounce works just fine. I have 2 SSDs mounted and could fit in a third without too much hassle.Using 20TB hard drives, you could have 160TB of storage in a case the size of a large shoebox. That's just nuts. FANTASTIC CASE and highly recommended.

the case is a little tight to work init's quality is ok only one hdd tray not lighting up ,tried switching trays but nothing works checked that tray everything seams ok but when i put it back in case still not lighting up so i think the led problem is on hdd back planesize of this case is perfect for the space i have it init has almost enough room in motherboard part to add 2 -2.5 sata ssd but mounts for only 1 so i 3d printed a mount that holds 2 price point it should actually be $30 lessproduct support is almost non existent. it came with no setup guide and has a ton of screws don't know which is whichso no i will not be recommending this nas case to anyone

when looking at other NAS cases on the market, you get cramped poorly cooled and limited space for boardsThis thing can support up to an matx board, multiple low profile pci cards, the cooling is great for the drives, decent for the motherboard and you get all 8 drive bays without having to make any sacrifices unlike some other brands....This product does have some quality control issues, 2 of my drive caddies seem to have dimmer lights compared to the others, and one of the sata connectors was damaged on one of the 2 backplanes but the seller is sending me a new board.over all even with minor quality control issues this is the best case on the market for anyone looking to build a home server, its small its quite, and it can fit as much storage as your heart desires.i would have given this a 4 star but in comparison to other cases available this is the best design, if the seller of this product starts listing replacement parts and extra drive caddies on amazon i have no doubt it will become the go to for anyone looking to build a home server.

I have three U-NAS 810a cases that are similar in design to this one. They are better build quality and noticeably heaver. The cooling is much better. The PSU mount is better. The included fans are better. Unfortunately, I haven't seen them in stock for over 6 months and don't expect them to return.I was excited that these were available and bought three for $180 each. Here are my thoughts:PROS- Hot-swappable 8-bay. There aren't many options.- Relatively low price compared to the few similar options- Decent-enough aesthetically.CONS- The fans are not good. While performing a scrub on my ZFS pool, I received an alert about drives being over temp. I looked and all of them were around 60C. This is bad! You can barely feel any air coming out the back. I immediately canceled the scrub, and the drives idle around 45-50c. For comparison, the U-NAS 810a with included fans the same drives idle around 30-35c and never reach 40c even during a scrub. This case -- same drives, same use -- 15-20c higher temps. The U-NAS 810a has 2 x 120mm Gelid fans instead of this with 2 x 90mm ??? fans. I am using these as an external enclosure (as I do with the U-NAS) and so do not have a motherboard installed, but can't imagine how hot it would get if I did. I will install a blank plate in the io-shield spot and hopefully direct more air over the drives, a fan controller to increase the RPM, and if that doesn't work I'll finally try new fans. I don't think this case has any right to advertise 'great cooling.'- I bought and set up 3 of these. When I powered on one of them for the first time, blue flashed from inside, the home's circuit tripped, and the outlet fried. I've built countless systems over the years and never, ever experienced a short. To reiterate, these are set up as an external jbod and only have the backplane and SAS expander connected to the PSU, so there's little room for error. After taking it apart, my theory is that the pins from the molex connector through the backplane was a little too long and shorted with the hard-drive casing. I have no way to validate this, but after putting a small piece of electrical tape over the molex power pins facing the hard drive, this didn't happen again. The manufacturer could either ensure the pins are not excessively long, or put some sort of non-conductive shielding between the drives and backplane.- The edges are sharp! They do include some basic gloves, which I thought was a nice touch, but it would be even nicer if the case never tried to cut you in the first place. This is not a unique issue, and not a deal-breaker, but be careful!- The PSU mounting bracket is terrible. I had to manually trim it because it covered the switch on the Silverstone 350w Flex PSU. It's a very flimsy metal that bends under the weight of the PSU. It would be much nicer if the PSU just mounted directly to the case, or if a stronger metal is used that doesn't interfere with the switch.If the U-NAS 810a is ever in stock -- buy that instead. The build quality is better (though it may still cut you), the power supply mount is stronger, the cooling is MUCH better, and it was only $20 more.If the U-NAS 810s continues to be out of stock -- this will do. It was a fair value at $180, but I see the seller has increased the price to $200. Comparing this at $200 to the U-NAS at $220, I could not recommend this. However, since there aren't really alternatives, this will do the job...
