External drive almost double of the price of the pc? you got to be kidding me

I did a few edits that I think should be fine. I assume you're looking into recording gameplay due to that 25TB external hdd. I personally think a 6TB WD purple will do you fine for now as a recording drive. The 2TB HDD is for your games/other stuff & the ssd is for your OS, you'll love how much faster it is than having a OS on a HDD.

Note: I selected the Kingston since I wasn't too sure if you wanted to spend too much on a OS drive or not.
