So Im building a new computer and im just wondering if I would be able to put in my existing Hard Drive with games and some files on it into the new computer, as it would make my life easier. Also to note this hard drive does not have windows on it.

So im going to be building my second pc as I want to start pushing for 144hz in most games at 1080p or 1440p for the near future, im also planning to run 2 monitors with this pc so im concerned if this all will work well together with how much im spending.
