Would this one work for Dell Wyse VX0?

By default VX0 uses small DOM connected directly to IDE on the motherboard. What you need is: 44pin 2.5" IDE ribbon cable, 2.5" 44pin CF/IDE adapter, and CF card of your choice, preferably "industrial grade". And for the capacity - I would go for bigger cards, at least 8GB.

I did unplug the card once and i found out it was made by apacer

Would this qualify:

or is the ide cable improper?

This one looks simpler. would this work if the unit was plugged in the right way? and I'm curious as to if the machine would close back up again. Otherwise I should probably do the cable approach

Yep, this is exactly what you need - https://www.ebay.ca/itm/124576928400

You need to connect it via ribbon cable, because there is not enough space for direct adapter (the second link you posted), certainly not with CF card inserted 😀 And even with a ribbon cable, you'll need to be a little creative with finding the place to seat the whole thing. I no longer have VX0, but if I remember correctly, I've used longer ribbon (15cm) and I've attached the adapter with CF card to cover with hot glue (and maybe zip locks) Hassle, but still much cheaper then finding DOMs with higher capacities 😀

And good luck with that particular thin client, two of them died on me for no reason, one day they worked, and then just... didn't 😒

Maybe connecting the CF unit to the cover with hot glue was asking for a short circuit.

What I did find interesting is that the price point of the DOM's themselves are not that much more expensive than the cable setup that you propose.

This one is advertised as a 2GB DOM that uses DDR1 RAM technology according to the seller:

and its price is only $5 more than the adapter you propose and the adapter doesn't include the CF itself.

I also found:

Would any of these be compatible and be able to fit nicely, even if I take the plastic off?

Edit.
OK. Maybe shipping is not very cheap if you are in Canada, sorry...

These DOMs will be usable as well, but they are just... less practical in my opinion 😀 You can connect CF card to main PC via cheap memory card reader to transfer data, it's harder to do the same thing with DOM. And CF cards are cheaper, you can get 8GB for US$10. Another thing - these cheap secondhand low capacity DOMs are probably very old, so question is - how long will they last, after all, it's a flash memory. On the other hand, you can still easily get brand new CF cards.

And for short circuits - hot glue is an electrical insulator, and one of my VX0 died with original DOM attached, so it's something else. And I'm not the only one with the same problem, see https://www.parkytowers.me.uk/thin/wyse/vx0/ - "At least a couple of my dead V90s did work initially and then stopped for no apparent reason." I don't know what do you plan with your VX0, but generally there are better options, for example HP T5720.

Here's my goal.

I made hardware that connects to any computer with special software via an RS-232 serial connection.

The problem is, serial ports exist only on older computers yet I still want to access the old hardware with today's computers. In order to do that, I needed something super compact that still has at least one serial port available with something for networking. This is how I got introduced to the VX0. With it, I can connect my hardware to it along with RJ45 cabling so it can connect to the internet.

As for storage, I plan to make much of the I/O occur from within memory, but I still need some sort of hard drive (DOM) for storage, and I'm currently seeking larger storage primarily for data files and also to test linux setups.

So far, I can't install "Damn Small Linux" because it requires 200MB storage yet I only have 128MB. However I can install "Tiny Core Linux". I'm going to go with the DOM stick first to see how that goes and if that runs terrible then I'll try the awkward cable and CF card setup.

I don't know what are your requirements, but you can try OpenWRT on this terminal. They have generic x86 build available.
I'm running OpenWRT currently on Wyse C50 (Via C7 1GHz CPU) as a router with ZTE MF823 modem.
Previously I used Wyse 9150SE (Geode GX2) for this puropose (Geode Build).

After all it is also (customized) linux with source code available.
