I found my favourite Dell: https://www.dell.com/en-us/shop/cty/pdp/spd/inspiron-17-7773-2-in-1-laptop/fncwscb6103s
Dell Inspiron 17 7000 2 in 1
But it has only an SSD and I wanted to ask you if it's possible to add an 1 tb of HDD disk
Looks like it - you will want to look inside first to make sure the cable is there for the drive and that the 2.5" bay is clear -- on some systems like this model, there are at least two battery options -- one of which takes space away from the 2.5" drive bay such that you would need the smaller battery to install the drive.
