Although the number of hdd mounting screws is a bit insufficient, it is a good product overall.
The case quality is awesome. Walls are thick, internal space is just enough to fit all your components (mini-itx + low profile cooler, HBA card or RAID card, etc.), it is well designed and all disk bays are PCB-based with "molex" power supply and SATA ports for data. Despite this, the problems you might face: - standard PSU 24-pin cable might be too short (at least it was in my Seasonic FLEX 1U PSU; - the delivery time can be considerably long (maybe, it was due to COVID-19 in my case) - the seller is unsupportive. They discarded my attempts to get pinout for chassis connector (power, reset, LEDs) and there is a clear language barrier.
The pinout (pin map) of the case connector (motherboard side): Yellow - PW SW; Blue - R SW; Green - HDD LED; Red - Power LED. All white wires accompanying the corresponding wires above are Ground.
