## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Mini-ITX Workstation Case
*by G***G on July 8, 2025*

Zero complaints. Great case for an mini itx build. I would say this case is for more workstation use over gaming, it has decent airflow but not what you would need for gaming, but if you're buying a case with a 200W integrated PSU that probably wasn't your plan anyways.Slick, easy to put together. Instructions are lacking but most cases are. Best for a compact desktop workstation build, monitor mounts, or headless setups where you just need a small form factor on a relatively middle-line build.

### ⭐⭐⭐⭐⭐ SLEEPER BUILD
*by D***P on May 9, 2024*

This case may look like it's designed for a boomer who works a 8-6 shift every day to escape his horrible marriage ... and it absolutely is. But don't let that stop you from throwing an APU in there and hiding it behind your TV so no one can see it!All jokes aside, this case is fantastic value. It has a lot of space for stuff I don't need like traditional HDD's and CD/DVD bays, but despite the wasted space, this case is still very small if you have a MATX motherboard.Thermals on the case are great, it has a massive open cutout where the cpu is which will basically serve as your intake fan. Turn the case upside down vertically and you'll have a perfect thermal solution. Fresh air coming to the cpu, hot air exiting the exhaust fan at the top and your PSU will be exhausting at the top as well. It's kinda funny because this setup gives me the best possible thermals yet it's technically designed to have the PSU on the bottom when vertically mounted with an exhaust fan blowing air out of the bottom as well.YES this case has standoffs, someone mentioned in a different review that it didn't. You don't need standoffs because the elevation is built into the case, you can screw any matx board in there and don't have to worry about shorting out your system.No dust filters, who really cares though, the more airflow the better.

### ⭐⭐⭐⭐ Makes a nice home for a NAS unit
*by D***C on July 18, 2021*

Here I review the InWin CJ712 case, which I use to house a DIY home/office network attached storage (NAS) device. It is my second InWin case, since for 8 years an InWin EM048 case has housed my DIY HTPC. Recently the electronic innards of the HTPC were massively renovated, but I kept the InWin case because it still was perfect for the job.The CJ712 case that I review here is almost perfect for its job as a NAS. Compared to other case choices on the market, the CJ712 has understated elegance in appearance, not the name of the case manufacturer in lights. The small 265 watt power supply is great, since my NAS consumes little power compared to other builds. Also, the CJ712 isolates its interior more than do mesh cases. Hence, the CJ712 avoids becoming too much of a dust trap yet still remains perfectly cool for NAS operations.I also like the front panel opportunity for a USB Type-C port. The black plastic case front is molded with a plastic insert that can be punched out, leaving behind a nice slot for a Type-C port. Given that offsite backup around here works via USB, I am ecstatic to have a 20Gbps port accessibly placed on the front of the unit.But this Type-C port also caused headaches. I could not find a way to use the hardware provided by InWin for connecting other hardware to the Type-C gap in the front of the case. I ended up drilling a small hole on either side of the front case Type-C gap so that I could screw a cable meant for a rear-computer PCI bracket into the front of the case, working as if the plastic front of the case were itself a bracket. Although using a plastic case front as a bracket generally is a bad idea, this ad hoc solution seems solid for now. That said, I shouldn't have to be using the front of the case as a bracket. InWin provides dedicated front USB 2 and 3 Type A ports; it should supply a physical front Type-C port, too. It's the year 2021, not 2000, after all. Type-C ports have become much more in demand than old USB 2.0 ports.Before ending this review I should address the close proximity of the CPU fan to the drive tray that is mentioned by other reviewers. I am steeped in the idea that CPU fans should discharge their hot air freely, so that having the drive tray just millimeters from the top of my Celeron 5925 stock fan did make me uncomfortable at first. But the objective facts are that the unit does not run hotter than other PC-like things in my universe and the SSD storage drives that are attached to the drive tray do not seem excessively hot after use. I've seen no apparent performance degradation due to heat, with the highest CPU temp reading at 51 celsius and the motherboard at 45. Thus, objectively speaking, there seems to be nothing wrong with the "CPU fan/drive tray" setup that gave me concern in the beginning. Nonetheless, this setup highlights a fact: although a great small form factor box for a NAS and probably also a HTPC, this likely is not the case for heat-creating gamers.**UPDATE**I found one specific heat problem. The drive tray hosts one 2.5" SSD on top at the rear and one 2.5" SSD on the bottom near the front. The drive on the bottom began to overheat, but only if I tried to move more than 500GB of data in one batch and did so at relatively high speeds (450 MB/s between internal drives). I don't try to do such things often but still I made a switch. I moved the SSD from the drive tray bottom bracket to the top, the part that is an optical drive bracket, since I have no ODD in this unit. I drilled a couple of holes for secure mounting via screws and moved the SATA wires, thus giving the SSD a new home. I tried the same data moving chore as a test and found that the overheating problem had gone.
