Upgrading my PC from worse to not-so worse. Need help if everything is correct or I am missing something.

Hi. This would be my first ever post on a subreddit. Not really used to writing those.

I am new to PC building, I know my way around but I just don't have the experience. So, I am planning to upgrade my setup a little, but I want to be secure that everything fits. So I'll just list out what I have right now and then what I will buy that will be replaced.

It's just that I did the research with the help of AI and I don't really want to trust it and I would prefer opinions on this one, not neverending agreement.

So we'll start with my present specs:

• CPU: Intel Xeon E5-2620 v2

• CPU Cooler: Unidentifiable Aerocool Unit.

• MBD: Atermiter X79 v1.3 (if needed I'll provide the photo)

• GPU: Asus TUF Gaming Nvidia GTX 1650 4GB VRAM

• RAM: 4x4 Samsung DDR3 (RDIMM) 1600 MHz

• PSU: Aerocool VX 500 Plus

• Memory: 1x Kingston SATA SSD 480GB

1x Crucial X8 External USB SSD 1TB

1x Seagate Portable HDD 5600 RPM 2TB

Hopefully didn't miss anything. And for now I am planning to change up the CPU and RAM to those:

CPU: Intel Xeon E5-2667 v2

RAM: 4x8GB Apple DDR3 (RDIMM) 1866 MHz

Will this work for me or is there better options?
