Inside the BRIX Pro - Part 1
Removing four screws, you can remove the bottom panel. As shown in Figure 8, there is a 2.5” bay at this panel, where you can install an SSD or a hard drive.
In Figure 9, you have a view from the inside of the BRIX Pro when the bottom panel is removed. At first glance, you can see two memory sockets, a Wi-Fi adapter, and a cable with a power and data SATA connector, which must be, obviously, connected to the 2.5” device you install.
Removing the motherboard from the case, you can see it better. The two SODIMM (“laptop memory”) sockets are for DDR3L 1.35 V modules (L stands for low voltage). There is a Mini PCI Express slot, populated by an Azurewave AW-CB161H Wi-Fi/Bluetooth card, which complies with IEEE 802.11ac (dual band) and Bluetooth 4.0. The Wi-Fi control chip used is the Realtek RTL8821AE.
There is a second slot (the black one near the Wi-Fi card) that is actually an mSATA slot for an SSD unit based on this form factor.
