I have a Gateway MX6421 laptop. I am looking to rebuild it and want to switch it to a new case. (I guess some people call it the chassis or whatever) anyway I tried to find a replacement for the one I have and the only one is well over $100. I need to know if my motherboard will fit into a case for another type of laptop since I have found the cases for toshibas and dells for around $30. Thanks for the help.
