This requires a NIFTY Adapter that connects your NEW SSD to your OPTIPLEX USB external port ~ HOPEFULLY a 3.0 connection but 2.0 also works too... it's just slower!
"Online" these Adapters start at about $4 from China... about $7 to $9 if you want it sooner from a US seller. I do notrecommend the Adapters with *TWO USB Connectors... a single connector is the better choice.
The Adapter looks like this: NOTE: 2 Adapters are shown. only ONE is needed (sorry that second photo won't delete)...

This Adapter Supports 2.5" Drives ONLY. I have used the adapter with SATA 2.5" (non-SSD) drives with no problems. Two tiny LEDs show power on and data action on the adapter.
BONUS! You can also do TOTAL SYSTEM BACKUPS with this Adapter and a detachable SSD or 2.5" SATA Drive... Connect the Adapter and Drive and power-up. Select as "BACKUP DRIVE"... SUPER easy.
NOTE: IF you are upgrading to SSD I highly recommend that you DEFRAG your current hard drive now. DO NOTDEFRAG if you are upgrading froma SSD drive to a NEW SSD.
IF your SSD is smaller (in capacity) than your current drive, AOMEI PARTITION ASSISTANT (I use V7.5.1). AOMEI WILL do that job for you ~ a few other programs will too.
"AOMEI Partition Assistant Standard" is FREE, but I'm not sure about Cloning to a smaller drive? That may cost for the full program? Find FREE AOMEI Partition Assistant Standard here:
Easily create a BOOTABLE USB DRIVE with the handy "Wizard" that is included. AOMEI is not the fastest gun in the west, but it does the job accurately ~ because the last thing we want is data loss or a drive that won't boot. AOMIE can also boot from CD (also made via the supplied "Wizard"), but the CD is much slower to load.
** NO NEED to open up your System now... you can Clone with the SSD connected outside of the case!
Connect your Adapter and USB Flash Drive... Now as you power-up... ready for your BIOS Screen, then select 'Boot from USB' AOMEI makes CLONING Super-easy! Often "F12" will get you to that option quickly...
After Cloning power-down and disconnect your adapter and SSD. Now open your case and your swap drives out. IF you SALT your original drive away as a backup or 'vault', you will have access to your original files and data in case of emergency!
If you hurry you can get a ADATA Ultimate SU650 2.5" 240GBSATA III 3D NAND Internal Solid State Drive for $26.99 ... ships free from California!
Note: I also tried the Adapter that has 2 USB Male connectors with a 5 1/2" SATA, but even with 2 USB connectors the Adapter didn't provide enough power/current to spin that drive up.
