[ITG] Can a HDD but added to this prebuilt?

https://www.microcenter.com/product/631691/powerspec-g164-gaming-computer

I like the smaller size compared to the larger but similarly priced G228

My main concern is if the smaller form factor means it won't have the space to add a hard drive inside. Judging from the pictures between the two, the internals are much more tightly packed in the case. I've never built a PC before so I unfortunately have no clue just from looking at the case

Appreciate any help, thanks.
