Not quite sure why I have all the cards...  I guess it's because I like to restore computers, so I like to keep most of the cards I get just encase I get a computer that it could of gone in...  And I didn't buy all this stuff.  Alot of it I got from my school.  I either could get parts out of computers before they where sent off, or I was somtimes able to get the whole thing.  Also, alot of the parts are from people who gave me old computer parts, like after they upgrade.
