As for verification, I don't think it's good to change from our current guidelines. So, CPU-Z, GPU-Z and score will be the only mandatory information. Manufacturer, productgroup and model would be optional (just as it is now).
Filters could be made, yes, but the database needs to be updated for this. As said before, there's no field indicating whether the CPU/GPU is mobile. Furthermore, we'll have to change something to the submission page, because it's not that easy to add 'notebook' information.
