I'm not very sure. On the MSI Claw 8 ai+ a modification was designed to install a 2280 SSD just like on the new MSI Claw 8 EX Ai+. In fact, it was positioned right ABOVE the heatpipe and none of the people who implemented the modification had problems in a year of use
The nvme disk is basically sitting on top of the CPU that can heat up to 100C during load (and will since this is a gaming unit). A storage flash chip is literally 2cm away from a heat source - a major design flaw, this will have huge negative impact on the storage and fast. Expect mass warranty claims in the next 6 - 12 months.
MSI's Claw 8 EX AI+ is the first device with Intel's first dedicated handheld SoC Arc G3 Extreme, which features the powerful Arc B390 iGPU. The result is a completely new level of performance, easily beating AMD's dedicated Z2 Extreme handheld chip.
