Possibility of 2nd hard disk
Contrary to what is stated in the specifications, this model has a slot for a second SATA, SSD or HDD drive, the choice is yours. There is even the caddy (disk holder) and cable already installed, and even the 4 fixing screws are included.
With this upgrade and adding some RAM (replace the 4GB strip with 8 or 16GB), you have a very well equipped computer.
Having opened it, it seems robust and well built despite its light weight.
Another unmentioned advantage: it is very quiet... Noise measurement should be mandatory!
The only thing missing in my opinion is an SD card reader, which is a shame, why such a petty economy on this model ???
