USB and audio ports

I have the following USB/audio ports that does not fit the floppy slot of my PC front panel. Grateful for advice on where this should be installed and how? Thanks.

 

UUUGGGG--- buy a top of the line case just to tear it up....
going back to really old school of MODDING your case.
back in the old days cases only came one
way & U had to make any changes to it yourself.
when I first came on the sceen there wasn,t any cases
with side panel fans. U had to make the whole yourself
and use a cardboard tube to direct the intake air
on to the CPU FAN.
In your situation a lot of the top cases have trays for
SSD drives. Some of the trays are made to fit into
a 5.25 slot. Figure out how to fit the device U want to
use to the tray & then make U some kind of front panel
to close off the slot but leave the connections
open for your cables to hook up.

 

Moving to modern times U could just junk your
device & just buy a new one already made to fit into
a 5.25 slot in the front of your case
