This Lenovo computer comes with a 128GB SSD while the Sirius 70 has a 240GB SSD. The maximum RAM capacity for the Lenovo is 16GB compared to 32GB for the Digitec computer.

Since this is not exactly specified by the manufacturer or he reserves the right to replace various components with other brands of similar quality, you have to own the PC yourself, open it and check what exactly is installed.
