Internal assembly
Two screws later, the cover is off and access to the single DDR5 SO-DIMM slot is possible. It is factory fitted with 8GB 4800Mhz Samsung M425R1GB4BB0-CQKOL.
If you remove both drive bays, you can take a first look inside. Due to the design, the view is somewhat limited, but one special feature of this variant of the Ugreen NAS is nevertheless immediately apparent.
While the M.2 slots on the big brother were still accessible via the flap on the underside, here they are located on the side next to the 3.5″ brackets. Apart from that, things are back to the familiar, the rubber covers on the back are fortunately not glued and can be removed quite easily with a tip.
Once the four screws underneath have been removed, the entire rear panel can be taken out. It is also held in place by four magnets on the screws of the fan, for whatever reason.
Incidentally, the fan has the model number A92DCLA23F6 and is held in place by four more screws. However, these are even rubberized, which is presumably intended to reduce vibrations.
Thanks to the normal 4-pin PWM connector, it can be easily replaced if necessary.
The inner “skeleton” is connected to the outer housing with additional screws, two of which are concealed under the soft foam covers.
Once again, the inner part can be pushed out to the front, leaving the front on for the time being.
Ugreen uses a total of two additional PCBs to connect the drive bays and the two M.2 slots.
There is no hidden third M.2 slot to be discovered this time, the operating system was installed on soldered eMMC memory.
Active cooling of the Intel N100 processor has also been omitted, although there is still an unused 4-pin PWM connector on the top edge. Apparently a change of mind was made during development, so it remains unused for the time being.

Maybe it’s the more compact size, but with the DXP2800, Ugreen didn’t use as many screws and hide them somewhere hard to reach. The complete disassembly is still not easy, but can be done with a little patience.
