Only if you have cable select, and your BIOS hasn't been previously
configured to boot from something else.

That's an assumption that can lead you to play with the wrong drive.

If you really can't tell which drive is which, this is the safest
option.  Afterwards, label your drives so you don't have to go down the
disassembly route, again.  Write onto the drive where you can see it
without disassembly (use white texta if the drive is black), enough
unique numbers from the drive's product code, or serial number, that
tally with what Linux reads using software.  So next time, you only have
to lift the lid.  You might want to label the outside of the box, too.
