Internal structure
If you remove all the data carrier holders, a separate backplane PCB is revealed, as used in most network storage devices. However, there is not much more to see from this side.
And if we turn our attention to the underside, the flap can be opened by removing the two screws. A small spring literally pushes it towards us.
Hidden underneath are the two DDR5 SO-DIMM slots, one of which is fitted with an 8GB 4800Mhz Samsung M425R1GB4BB0-CQKOL bar. The two M.2 NVMe slots are also located here, which I’ll come back to in a moment.
When I finally arrived at the back, I had a bit of a rollercoaster ride of emotions: no screws to be seen, just rubber covers. I had already mentally prepared myself for the annoying task of unwinding the glued plugs, but to my surprise, they are only plugged in and can be easily removed with a screwdriver.
Four screws later, the rear cover can be removed, which for some reason is also magnetically connected to two screws on the fan. This is next and is held in place by four more screws.
Fortunately, we are dealing with a normal 4-pin PWM fan, and the fan header is also easy to reach. Replacement in the event of a defect is therefore possible without major problems, very good. Incidentally, the fan was manufactured by Fan-Cooling and has the model number FD14025SM1.
We have now apparently reached the point at which Ugreen would like to dissuade the customer from continuing to advance. Apart from the fact that the warranty seal is not valid in our jurisdiction anyway, the sticker was also easy to remove in one piece. Removing is also a good keyword, because no less than 12 screws are used to connect the inner frame to the housing.
Once you have removed them all, the cage can be pulled out to the front. Payattention to the small spring-loaded pin at the M.2 slots, otherwise it will get jammed in the opening.
And lo and behold, another M.2 slot appears! Ugreen probably doesn’t want you to have easy access to the SSD with the operating system.
This is a Phison E13T YSO128GTLCW-E3C-2 with 128GB capacity. According to the PS5013-E13T NVMe controller, it is connected with PCIe 3.0 x4.
And another 5 screws later, the mainboard is finally removed. The Intel Pentium Gold 8505 processor has been equipped with active cooling, which is probably a good idea with a short-term TDP of 55 watts in Turbo mode. The 10GbE NIC is also at least passively cooled. The interface for the SATA board is also located here at the bottom left. The BIOS chip is permanently soldered, but there are pins directly underneath, which are most likely used for flash in the factory.
On the other hand, there is not much new to discover, perhaps the pins for UART are still interesting for some people. But at least you can get to them without having to dismantle the whole NAS.
For those interested, here is the output from Lspci:

And, counting, how many screws were there in the end? I think it’s obvious that accessing the OS SSD or BIOS battery is not trivial. But it doesn’t detract from the very high-quality feel of the NAS; for a first attempt at this brand, the feel is surprisingly good.
