Lao Zhang NAS Case Integrated Power Supply Backplate (no more external power supply, no more worrying about too many hard drives not being powered, supports up to 500W power supply)

This is a backplate that allows a server power supply to be built into the case. You can slide the power supply into the case just like a hard drive, which is very elegant

The hard drive next to the power supply has an additional 40*40 fan, so there's no need to worry about heat dissipation. This power supply is especially quiet; my NAS currently doesn't have the capability to make the fan of this power supply run

For hard drive power, you can choose a DC to SATA power module. I have currently tested an 8-disk power module, and it fits without issues

The fan size is 40*40*10 12V. You can buy 18V ones or 12V ones with lower speeds. The biggest noise in my case comes from these two fans

The opening for the switch I made is 20*12. A common 19*13 switch can be installed. This switch is used to control the power supply (there is a wiring modification diagram below, this is the only place where a soldering iron is used)

For my power supply, the leftmost three pins are shorted to turn it on. You can short pin 23 like me, and connect the two wires of the switch to pins 1 and 23 respectively to control the power switch

The picture below shows the power supply specifications. Everyone can buy or find a server power supply of similar dimensions

The hard drive power supply is a DC to SATA eight-port power module, and there are currently no issues. Everyone is welcome to discuss better solutions
