Is it possible to add a HDD to a desktop that came only with an SDD

[MattEUK]

I'm looking at buying a HP Pavillion 24-k0012na, however it doesn't have enough storage and I'm wondering if it is possible to install a HDD to it, given that the desktop doesn't come with one at all. Will those pose a problem to the desktop accepting it? Also, can anyone recommend a good supplier for it? 

Apologies if they seem like stupid questions but this is the first time that I've considered swapping parts for a desktop and I don't want to mess it up or buy something unsuitable. 

Thanks in advance!!

Hello
I advise you to call an **bleep** in your country

the computer, is this one

unfortunately, there is no mention of the available sata ports
even less locations
We find another similar model with the same motherboard, only this does not answer all the questions, available location, available connectors or not etc.

You have this manual, but it doesn't prove anything either

Now you can opt for an already equipped model.
If you absolutely want this model, which Hp is not able to answer, there is the option of the external hard drive.

Sometimes the models in this family come with the 3½" bracket for a mechanical HDD, sometimes they don't.

Quickest & best way is to have a look yourself.

Lay it on it's back, pry off the speaker cover (it's only clipped in) then remove the 10 or so phillips screws under the speaker cover. Then with a plastic pry tool, pry the clips around the edge of the screen. Then the screen will pop out and you'll see the mainboard under the panel.

yes, I have already answered the question the fact is that the user does not have the computer
