Although all SKUs may look identical, their sizes are very slightly different between them due to changes in the cooling solution and GPU. We've compiled all the size differences here so potential buyers can more easily compare the Blade 15 versions before committing to a full purchase.
https://www.notebookcheck.net/Razer-Blade-15-series-now-has-a-total-of-four-different-thicknesses-depending-on-the-SKU.393891.0.html
Every SKU should integrate 1 inch thickness to accommodate a bigger battery, 9mm 2.5" drive bay, and a cooling solution that can actually cool a 2070+ Max-Q. At the moment, this laptop clearly cannot handle anything over 8750H and 1060.
