SSD's are universal as far as you're concerned. it will use the same sata cables your hard drive uses.
and they all plug in the same way.
I personally only use Samsung SSds bc they seem to be the most reliable.
Last thing you want is spending all that time setting up, then your SSD dies in 3 months... seems OCZ's die frequently.
depending on the age of your system, you will want to go into bios and make sure your SATA channels are set to AHCI, which is much faster for SSds, but is still backward compatible if you're using your seagate as a 2nd drive
