AMD's reference GPUs are all made by PC Partner Group.

You are supposed to put them in at the same time while those tabs are underneath the bit where they're blocked now.
Or in a way, 2 pin first, then 6 pin.
Not the other way you have them now.

The SSD is capable of PCIe 4x, laptop has it wired for only 2x.

Those SlimSAS ports are for PCIe only. So U.2 for example, not SATA.

SpecDB is a pretty good option.

It's behind the M.2 heatsink that you can see in the bottom left corner of the image.

I count 2 NVMe slots?

As the manual says, ports 5&6 are disabled with M.2 device so you can still use ports 1-4.

Maybe one of SilverStone's cases could work? Perhaps RM44?

Integrated Graphics Processor:
1 x DVI-D port, supporting a maximum resolution of 1920x1200@60 Hz
* The DVI-D port does not support D-Sub connection by adapter. 1 x HDMI port, supporting a maximum resolution of 4096x2160@60 Hz
* Support for HDMI 2.1 version, HDCP 2.3, and HDR. The DVI-D is only single link and as such only does 60Hz.

There's 6 SATA ports.
4 next to the chipset on the edge, 2 at the very bottom corner.
So the NVMe takes away 2, leaving you with 4.

I bet it's currently between the motherboard and case, just rattling in there.
So open the other side of the case and look for it or tilt the case, maybe it'll get out or remove the motherboard to get at it.

Maybe AXIS Companion Recorder? Fits your mom's requirements.

Good selection of cameras.

Best option would be to buy a modern PSU that actually has a proper PCIe power connector instead of using that ancient PSU with a Molex to 8-pin adapter.
Your PSU most like isn't able to provide enough wattage.

What you most likely have, is an DVI-I to VGA adapter, and your RX 550 only has an DVI-D connector.
DVI-I has analog pins, DVI-D doesn't.
So you need to get an active DVI-D to VGA adapter.

Delock makes one with Thunderbolt. Close to 2x price of their USB 3.2 Gen 2x2 enclosure.

What you have is Registered ECC memory which only works with EPYC.
Ryzen supports Unbuffered ECC.

The chipset quoted here has 12 PCIe lanes. The CPU meant for it has 20 lanes. So that's 32 combined.
AMD Ryzen CPUs have 20 lanes and the AM4 chipsets can provide anything from PCIe 2.0 x4 to PCIe 4.0 x16 depending on which you choose.
So they're comparable.
