This is an M1 Mac Mini with a 1TB SSD and 16GB of memory. As an accessory, I'm including a Satechi hub that can house an SSD (please note the type of SSD required). There is a specific bug with this model where static may occasionally appear on the screen when using an HDMI connection. To address this, I recommend using an HDMI connection via Thunderbolt. I will include a conversion adapter. Please see the third photo. Thank you.
