Looks pretty good. I would advise skipping HDD entirely for a gaming build. You can get a similarly priced M.2 SSD which will perform significantly better, be easier to install, less prone to failure (at least mechanically) and be tidier cable management wise. I haven't used an HDD in a long while, but I have no reason to anymore. For a workstation, you should still aim to use an SSD as your "OS" drive, but HDDs make more sense when dealing with large amounts of data.
Fan wise -- anything from arctic should be sufficient. Look up build guides for your case to see what size you need, and then decide if you want RGB or not.
