Thank you! I decided to buy a 2TB SATA internal hard drive, which should be arriving tomorrow. I was a bit sceptical about installing it myself, so I looked up some tutorials and it turns out it’s actually one of the easiest upgrades I could do. At first, I was nervous because this is my first ever proper PC, and I bought it pre-built, so I didn’t want to risk breaking anything. I went with the SATA version instead of the USB one since it’s apparently more reliable. Hopefully I can get it working without issues I’ll try to post an update once it’s installed.
