TL;DR - seal off the side vents to force airflow over the drives and reduce temps. I'm using this for a TrueNAS Scale based home file server. Motherboard (and CPU) is a Supermicro A2SDi-8C-HLN4F. I added a Solarflare SFN5154F (single port SFP+) 10Gbps NIC. System boot drive is NVME m.2. Storage drives are two 4TB 2.5" SSDs, and four 14 TB 3.5 spinning drives. I'm not pushing it too hard, but everything works fabulously. The only app I'm running is Nextcloud. I have another big server running Proxmox, and this fileserver is the backing store for all my containers and VMs, as well as storage for everyone in the family. I'm writing this review mainly to suggest to others a (likely) way to improve drive temps: close off the side vents on the chassis. I used black construction paper and aluminum tape to seal off those side vents. To be fair, I did not take before and after temperature measurements - sealing those vents was the very first thing I did. But the idea is sound: we want to force the airflow (from the 120mm chassis fan) through those drives. With those big vents in the side of the chassis, the airpath will short-circuit, and little to no airflow will pass over the drives (unless you use a crazy high RPM industrial fan). Note also there is room for a larger 120x38mm fan. In the spirit of full disclosure, I did replace the stock fan with a Delta AFB1212SHE-PWM, but it's only running at 800 RPM. In hindsight, I really don't think this was necessary. The stock fan is likely fine, but if I were to do it all over again, I'd take a hard look at the Arctic Cooling dual-ball bearing "CO" (continuous operation) fan (ASIN B07GSRRHZT), Nidec Servo GentleTyphoon (ASIN B017UX9DRA), or Noctua NF-A12x25. Most of my drives live around 35C, the hottest one will sometimes hit 43C. I think these temps are perfectly fine for long-term health of the drives. I'm using the included 265W Flex PSU that came with the unit, and it's working fine. My whole system only uses about 50 Watts (measured from the wall with a Kill-a-Watt). Usually the power supply is where I don't like to try and save money, but I'm hoping that with my low power draw, and the fact that InWin is a huge OEM, this power supply will last for a long time. If the power supply fails quickly, or you want to replace it right away for a better brand, then I don't think this case would be a particularly good value. I.e. if you consider the advertised price for just the case without the PSU, then there might be better options (but I haven't tried them). But based on how happy I've been with this case, I'm about to buy another to build a similar NAS system for a friend.

Excellent product, great supplier to deal with.

Bought it back in 2019 for a few bucks less than it is now, almost 3 years later. Although, mine came with the 265w bronze SFF PSU. InWin also sells a gold 350w SFF PSU for this case, but upon request for a quote a few months after the purchase, they quoted almost the same amount as the case which was too pricey for me. Anyways, the case is tight to work in, but the removable MBO tray at least somewhat helps. I paired it with a cheap B550 Asrock Fatal1ty Gaming ITX board, an Athlon 200GE, 16gb RAM and 4 Red Plus drives, and stuck an NVME to the back of the board which is not ideal, since the poor thing goes over 60c under not-so-heavy loads. There is some clearance between the board and the MBO tray, but not enough for a passive heatsink, but that shouldn’t be a problem for motherboards that have NVME slot on top of the board. Speaking of heat, the drives are cooking in this thing. You should be ok with smaller drives (4 and 6tb Red Plus ones), but anything bigger and the temps are not so comfortable. 8tb ones were always around 45c in idle and lower 50s under load, and the 10tb ones are in lower 50s in idle and up to 59c under load. Still a few degrees lower than max, but still way above anything that should be considered reasonable. Also, I recommend getting a MBO that has its SATA ports in the lower right corner, instead of upper right or, worst option, in the middle of the side of the board, because they will sit right under the middle of the HDD cage and it will be a major PITA to plug/unplug them. That being said, my HTPC died just the other day and still waiting for a replacement PSU and MBO because either one or both failed. I suspect the PSU because I think it overheated. We moved from US back to EU and as the memes say, there ain’t no AC here so the entire computer was getting pretty toasty (despite the low end hardware), and since the PSU fan became noticeably louder under load, I presume the included PSU gave up. I mean, everything is still spinning, no bad smell coming from PSU, but the PC will not post. Will update the review when I pin point the culprit. Speaking of high HDD temps, I have decided to stick a 120mm Noctua Flex under the HDD cage with either zipties or doublesided tape, since there are no screw holes for a fan there. There are three diagonal cutouts under the HDD cage and 3 of 4 drives will be getting at least some airflow that way. There are smaller cutouts on top of the HDD cage, but they are too small and there is enough space to stick a mere 80/92mm fan there, in the slim ODD slot, but the fan will be choked by the top panel, so that is not ideal. Still do not know where the air pushed from under the cage will exist, hopefully the rear 120mm Noctua Flex will be enough to exhaust some of it. There is also space in front of the case and under the hdd cage to stick, according to my not-so-expert measurement, 2 maybe even 3 40x10/20mm fans, but there is a lot of plastic and mesh on the front cover so the airflow will be questionable. If the 120mm under the HDD cage does not help, that is my next step. As for the PSU, it has to be SFF. FLEX will not fit, IIRC. Now, there are a few available here in EU, but most are FSP ones that have the fan on the front of the PSU, so the hot air from PSU is exhausted into the case. And even if it is a modular one, you will have a decent amount of cables tucked right in front of that fan, so again airflow is dicey, to saythe least. Therefore, I had to opt for a PSU that has the fan on the back of the unit, Silverstone FX350. All good, but the fan on those is reportedly extremely loud. People have been replacing it with 40x10mm Noctua ones, but then the PSU overheats since the 40x10mm Noctuas are too weak. And 40x20mm will not fit, since the original fan is 40x15mm. There are some guides for Delta fans (internet is your friend for the exact model), which are 40x15mm, but then you have to switch polarity on the fan and some people reported 100% success, while there are a few that did not fare well. I’ll give it a try with the stock fan and I will be adding a 40x20mm Noctua on either the side of the PSU or in front of it, to supply air from the case into the PSU and hopefully the stock fan will exhaust it through the back of the PSU. And if that fails, well… I guess I will be modding it as well. All in all, thank you for reading my blog and beware of the temps in this case. I am still looking for different solutions, different cases, but they are either much bigger (Silverstone ones, for example), or the layout of the case is even worse than this one. I’ll give this one another chance, because I do like it and I wish InWin would make a few revisions, maybe increase its size by 10-20% or come up with a solution that would include a fan for the HDD cage. Oh, and if you have AC and you crank it to 68F, forget the troubles with the overheating, you should be fine, lol.

Really great case for a home server build. You need to get your own SATA cable. Manual is not included in the packaging but can be found on inwins website

This case was exactly what I was looking for. A 4 bay, ITX NAS chassis that is small, and isn't super expensive. That turned out to be not such an easy task. The only other option I could find that was readily available was a SuperMicro chassis that was basically the exact same as this one, but more expensive, and required a front panel wire adapter if you use anything but a SuperMicro motherboard. It has a good, if maybe a slightly loose slim ODD mounting system. I used this bay for an Icy Dock 2.5" hot swappable bay(12.7mm model). The thermals are pretty good, but not great. It seems the rear fan ends up pulling a lot of air through the side vents instead of through the hard drives. So I put some painters tape over the side vents( I may be doing the same to my front vents soon too). The product page doesn't specify, but this 100% comes with the 265w power supply. On that note, it is very good. The fan is pretty quiet to where I couldn't hear it over the hard drives. and even with my ear right next to it, I heard no whining or hissing coming from it, which I was not expecting. I was really expecting it to be kinda garbage. It also has all the perfect cables for the case, at the perfect lengths, with an extra set of two SATA connections, just in case you need them. I think the biggest downside for my on this case is the backplane. More specifically, the fact that it doesn't pass through the HDD temperature data to the SATA controller. SMART data does, just not live temperatures. So in TrueNAS, I can't monitor the temperatures in real time, I have to wait for it to finish a SMART test, and then read the results of that. If it weren't for that, the backplane is fine. it can control the fan if you want, and can have its fan curve changed with some DIP switches. Along with a GPIO header which it provides a pinout for, but I'm not actually sure why it is there or what can interface with it.
