+ an 120gb ssd i might remove to use for another pc.




 

Sabrent rocket, Intel 660p, those are pretty often the best budget contenders

Compared to a mechanical drive their power draw is very low, I wouldn't worry about it. Overall consumption is less that 7 watts.

All of the M.2s on that page are solid units.  Samsung would be the most premium, probably, but all of them will get the job done without a notable difference in speed.

ok thank you

Any 2.5" SSD will be compatible with your board.  Just make sure you plug the SATA cables into the yellow ports on your board.  The black ones (at least according to this picture) are SATA-II ports, which will bottleneck any SSD (they're fine for HDD's though).

You would want an SSD for booting, and not storage if you have desktop. SSD only come in 2.5" for SATA.

no, you can have a 240gb SSD and a 1tb hdd just fine.
I'd suggest putting windows and frequently used programs on the SSD (chrome, steam and stuff), as well as a few games that take a long time to load. All your other extraneous files can go on the HDD.

Then a straight clone will not work. You will need to perform a fresh installation of Windows.

As long as everything else is remaining the same(mostly the motherboard), the code should be able to be used again. The hard drive can remain the way it is, but when you install Windows, disconnect the hard drive to prevent Windows from screwing with it. If you go through the installation process with the hard drive connected, Windows might install a System Reserved partition there instead of the SSD, and effectively the hard drive will be tied to the system. If the drive dies, or otherwise becomes disconnected from the system, Windows may not be able to boot. 
 
Once everything is done, you can reconnect the hard drive(if you don't have hot-swapping enabled, turn the system off and reconnect the drive), and delete all the Windows stuff off of it and use it as a normal drive.
