Looking for the same lead. I have the Aspire ES1-132-C4K5 with the same paltry 32GB storage and THAT is the issue. Not enough space to update Win 10! There is a space underneath to install a 2.5" HDD or SSD but unfortunately it's not a standard SATA connection but some Acer specific cable needed.
Are you sure you mean 'HDD cable'? The reason I ask is that as far as I know this Acer model uses a 32GB eMMC flash drive which is soldered on to the mainboard. This could explain your difficulty in finding such a cable.
