I wouldn't call the screen matt. Rather, it reproduces glossy colours. The brightness is just below the comfort level in front of a window with incident sunlight. The bottom can be removed easily with a mini screwdriver and the various modules are easily accessible. There are 2 memory slots, only one of which is occupied. It's best to order a second slot right away. Processor, SSD and HDD are also plugged in and can be replaced. I think the graphics card is integrated in the motherboard (there are wildly distributed bugs under the cooler plate and nothing plugged in). Greetings Sam
