When it comes to gaming PCs, size is, of course, everything. Weight too. You just know you're going to get a better experience from something you can barely lift, and which takes up as much space as a small refrigerator or drinks cabinet, than you are from something more slender and—dare I say it—portable.
There's a bit of truth to this, as a larger case has more room for airflow, and a bigger PC can simply take larger components (and the top end of the graphics card hierarchy can get surprisingly big) but as anyone who's used the Acer Predator Helios 18 knows, size isn't everything.
