I think we are getting into the "what is a laptop" discussion.
If you're taking it apart to clean and have easy access to the GPU and CPU, you probably have a 'performance' laptop which is noticeably larger and heavier then the type of laptop Moonshine Fox is talking about which was probably a 'portability' laptop and so noticeably lighter and smaller.
(I'm assuming here of course.)
Really, there's a huge range of features, this one in specific being how portable do you need it to be?
You can dedicate a backpack to moving your laptop around? That allows for a larger and heavier unit then if you are limited to carrying it in a small shoulder bag of some sort.
Not to mention user interface, one of the biggest reason I prefer desktops over laptops is the full size mouse and keyboard.
