You may want to note any cables that might come with it (if any) and also note the MotherBoard / Computer it came out of. Also might want to put a model number of the item to see if people know how to find out if it's compatible with their system.
ok Well Your best bet is to note the Motherboard Make and Model or system it came out of like Dell, HP etc (Example: Dell Inspiron E350 or Intel Motherboard E3748). Just a suggestion because these aren't always compatible with every system.
All I know is came out of my old HP i had i dont know the mother board or anything like that i'm not all that computer savy I just have a couple of my old computers and I figure people can use some of these parts
