I don't have a specific recommendation but, maybe, a bit more info might help.
Is low power consumption a primary objective?
When you say "5 drives" you're getting out of the typical "USB box" range which is typically 4. Beyond 4 drives, costs go up. At that point, with 5 or more drives, a used server begins to make sense.
I suppose on my DL380 Gen10 I could get a USB-C card and go that route but how does that work? Will OMV see, through the USB-C the 4 drivers
There's no way to answer this without more info on a specific card.
Would something like this work for me? And via USB-C and OMV RAID Software I could Software RAID?
I took a quick look at a few of the reviews. There is at least one that said it worked with Red Hat 8.
I can crate RAID array or will anything I get have it’s own OS where I create the repair and OMV would Simply mount it, through USB-C?
"Creating" RAID over USB is not supported in OMV's GUI. (Why? Because it's risky.) However, you can create an mdadm array on the CLI and (in most cases) it will be recognized by the GUI. Your call.
network attached storage = NAS (ie. OMV, Freenas, or some proprietary box)
RAID = some kind of controller to direct traffic and/or handle checksumming (ie. a NAS or a RAID controller).
You can get external RAID boxes, but anything USB connected is not really recommended in linux as a long term connection type, Particularly if you are trying to make a mdadm RAID. eSATA or SAS will work better as a long term connection, but will be more expensive and require the connectivity on the system you are hanging them off of. A SAS JBOD can show multiple drives but eSATA and USB are normally single drive connections if you don't have a RAID controller in the box.
Well, here are some esata RAID enclosures. Pair them with an esata card or sata to esata backblane to poke in the system and "bob's your uncle."
If your current server can take an LSA SAS HBA card, hang a DAS box off it. Buy or make the DAS box yourself.
I do have a LSI SAS9220-8i Card.... Sitting in a box. But being the OMV Server has available SATA.... Too many options.
The LSI SAS9220-8i card can talk to SAS or SATA drives via its eight ports.

Hmmm, Unless I do not understand what I am looking it, this has 2 Ports... Pic is off the WEB but it is my card. Being it has to external inputs, how would I connect an external storage box to it?
Sas is a better option for sure, but if you can’t put the drives in the system, that is an internal card, so you would need an external sas drive enclosure and an internal to external sas adaptor. Once you combine sas and enclosure in the same sentence, the price starts to go way up, as sas is considered more of an enterprise type of connection.

If it’s an 8i, there should be a couple of cables that fan out to 4 drive connections per cable. As I said though the “i” is internal. Changing to external requires an adaptor and the right 4 channel cables
You are mixing too many different and incompatible technologies into one conversation.
Well, I wont deny that.
Enclosure;
PCI Express Card;
Will this work?
Should work together.
But I wouldn't get involved with any eSATA gear. You can do essentially the same thing but in a much more flexible and future proof way with a SAS card with external connectors and a DAS box with external SAS connectors.
