Will an Inspiron 1520 Motherboard fit inside an Inspiron 1525?

The title says it all. Just wondering if I can give a slight boost in the graphics department.

 

I don't have a definitive answer, but it's probably similar to the situation with the 1501 and the E1505. You can put a 1501 board in an E1505 chassis, but there will be non-functional buttons and empty ports. On the flip side, you can put an E1505 board in a 1501 chassis, but you have to cut holes for some ports and lose some media buttons, etc.

Might be better with the 1520 and 1525, though, since both are Intel boards. I'd say the possibility of the swap working is "fairly likely". Nonetheless, even if the swap was doable I wouldn't recommended it... you might be getting a small boost in graphics, but you'll also be subjecting yourself to the whims of an Nvidia 8-Series GPU that has a long track record of failure.
