Power Spec G705 hard drive upgrade

Greetings. Yes that has 2 2.5" and 2 3.5" drive bays available. We have an article for that case on how to locate those bays: https://community.microcenter.com/discussion/2868/tech-article-how-to-locate-the-additional-drive-bays-in-a-lian-li-atx-205-case

You can use any 2.5" or 3.5" drive there, there isn't a specific part you are looking for. Windows etc. would be installed on the m.2 drive screwed in on the motherboard, if you wish to replace that you can use another m.2 drive, again, nothing specific needed, you would have to reinstall Windows/programs to change that over.

Could I  clone my existing m.2 drive with Acronis software and replace it with a 2tb m.2 inland pro m.2ssd then I'm thinking of adding a 2.5 in. ssd in one of the open drive bays. 
Thank you for your first answer and link. 

Yes, you could do something like that if you would like.  I personally prefer backing up data, doing a clean install and redownloading any programs because cloning can be finicky at times, but that's just me.
