The unit is not ultra-compact but not big, as it measures W x L x H (16.9 cm x 12 cm x 5 cm) in size (which is not big) and weighs 899 g. The Beelink GTR7 Pro has a lot of options for ports and caters to individual requirements effectively. It includes, e.g., USB 4, HDMI 2.1, and DisplayPort 1.4.
At the bottom, you see two big rubber pads; the anchoring to the support surface is very good.
The Beelink GTR7 Pro also includes a wall mount, allowing easy attachment.
The cooler used here has a vapor chamber, so it should improve the temperatures (but this is not user-serviceable/accessible).
The Beelink GTR7 Pro uses the Wi-Fi 6 module, offering high and consistent data transfer rates on a 5GHz network; they are more than adequate for daily use; more on that in the network chapter of this review. Both SSD (NVMe, 1 TB) and DRAM originate from Crucial. The M.2 drive is a Crucial P3 Plus (CT1000P3PSSD8).
The unit has two 16 GB DIMMs (dual-channel is possible; you can find 32 GB onboard); those are CT16G56C46S5 modules.
