What do you do with that PC to require 128GB? What kind of memory did it ship with? Also does the unit ship with a heatsink for the NVME drive?

This is an office computer, which uses primarily Microsoft Office. It's use definitely does not require 128GB of RAM.
The specifications that it shipped with are:
+Processor 12th Generation Intel Core i5-12500 Processor with vPro (P-Core Max 4.60 GHz with Turbo Boost, 6 Cores, 12 Threads, 18 MB Cache)
+Operating System Windows 11 Pro 64
+Graphics Integrated Intel UHD Graphics 770
+Memory 8 GB DDR5 4400MHz
+Storage 256 GB PCIe SSD Gen 4
The NVME does not come with a heat sink.

Hi, I am think to buy ThinkCentre M90s 4 gen but the support Memory Frequency in mentioned 4400Ghz similar to M90s gen 3 . I have searched online about the 4400Ghz Stick RAM but didn't found. I Noticed you have inserted Crucial Memory stick with 4800Ghz. how it is supported . I have also seen 3200Ghz in your BIOS. why it is reduced ??
