> to not throttle under load Then you need a thicker, not thinner one. More vertical space - more space for the heatsink - more heatsink efficiency. But the other comment is right, nor SO-DIMM, nor CAMM would share the space with heatsink/fan/blower. Eg look at this ultraportable [0] inner space. The whole motherboard with CPU, PCI Wi-Fi card, north and south bridge and 4 memory chip takes space of roughly a CD-ROM drive. If you could see the whole notebook you would see what the whole notebook consists of two parts - one is the ODD, other is mobo. And this is a notebook from 2006. We can do compact notebooks for years, it's not a problem to make small, light, thin notebooks. The only problem is making light and powerful notebooks, but they can't be thin by design, because more power - bigger battery - bigger case both for battery and (usually) for a bigger screen. But in 99% of time you wouldn't notice the difference between 18.6mm and 19.6mm.
