The opposite area of the barebone does no longer have two separate openable partitions, but a single, larger one, fixed by four screws:

After opening up the case, we will start noting visible improvements! On the inside of the cover we will observe a large aluminum heatsink with two different heights, but also an easily removable (screwless) 2.5’’ drive bay:

Here is a closer look on the drive cover:

This was mainly designed to absorb the heat from the M.2 storage area, but also the memory modules so these won’t throttle or overheat:

The 2.5’’ storage bay is easily accessible; a separate screw is not needed anymore to lift it up for installing an extra drive to it:

Mechanical drives do sometimes have exposed components on their board, so Shuttle saw fit to also include a black separation layer in this area:

Here is how the board does look with the tray removed; cabling can be observed for the VGA port, the SATA Data/Power port, but also the two preinstalled antenna interfaces (Wi-Fi):

The top M.2 slot can accommodate 2280 drives and has support for PCIe Gen4x4 but also SATA drives; the secondary M.2 slot will accommodate a PCIe Gen4x4 SSD in 2280 format or a WWN04 kit with 4G/5G card (sold as an optional piece of hardware):

Nearby, we have the M.2-2230 slot for the optional WLAN card:

Two SODIMM slots are available, supporting up to DDR5-5200 as per i7-1355U support sheet from Intel; higher frequency DIMMs can be installed but they will only operate at 5200MT/s. The maximum supported capacity noted by Shuttle is 64GB, so we will be allowed to install up to 2x32GB modules:
