T5810 MODS & Notes

Hello,
I'm new member, just created an account. I like my rig that I just bough. Posted an image for good reference.
- I have questions
- There are few things, i'm not familiar with.
I have HDD and some gen SSD SATA plugged into sata ports.
So, two HDD that im looking to revamp.
GOAL:
1. 2TB m.2 nvme (OS running) or something better THAN the one I currently have SSD SATA
2. for Storage I want to move to PCIe.
Pcie adaptor from amazon and (2) 2TB M.2 on that card. for storage.
3. That video card I have.
I need to bump it up to Quadro M5000 (150W stock)
Memory is at 64gb
NOTE: Will be updating the bios with putting storage on pcie? or will the pcie will pick it up?
NOW, will that 425W PS handle the upgrade
I'm hoping to make this ONE stop thread for all the topics.
Thant way, it can be seen, how it all came together.
BASICALLY: Who else has this set up? Got pictures? What kind of mods made to you T5810
TECH:
What is the tightening torque spec. Like, how tight, should I be tightening that HEAT sink?
I'm planning to pull the heat sink off and put some fresh (current) thermal paste.

Mods...heating issue overclocking a 1650v3. Went to a supermicro 4u cooler that had to be modified to bolt down to the Dell standoffs. Made a vrm heatsink from an old one I had lying around and yesterday modded a chip programmer to pull the bios from it so I can totally unlock it and have full overclock control. Bios is pulled now to start changing stuff on it. Hoping for an all core stable 4.7ghz overclock.
