So my brother bought a "Modified" Acer Aspire E15 E5-571P From someone And Apparently he has 2 hard drives yet also a disk drive which makes me think there's not much room in the chassis of the laptop also, as far as i know, there's no Extra m.2 or nvme slot so I opened my laptop up (same one as his.) because I recently had to change the drive so can someone explain to me how he did it because he has 2 HDD or SSD's in his laptop and as well a functioning Disc Drive so Did he Brute force it in there or did he do some modification to the chassis or moved parts around?
