Question Pavilion MS225 Motherboard upgrade?

[sandbox242]

I recently was given an old Pavilion all-in-one MS225. The specs are trash. This is the motherboard: https://support.hp.com/us-en/document/c01815036
I'm wondering if/where you can buy a newer motherboard with the same form factor and same IO layout that I could swap out with newer and better CPU, GPU and RAM support. I'm thinking maybe it's possible they released a newer generation of the same series or something? Can't seem to find anything and I'm not quite sure what to search for.

I was also considering the fact that the power supply is external. Would it be possible to at least upgrade to a more powerful CPU that fits the same socket if I can get a better power supply? The stock one is only 90W.

There was an effort about five years ago to market All-In-One PC builds, however there was not a lot of interest in it.

The selection of motherboards for such builds is Thin-Mini Form Factor and Thin Mini-ITX AIO Convertible Chassis. There is not a lot to choose from.

I don't know of anything for your current HP case.

I eventually found some similarly styled machines like the HP 400 G1 or the Business Desktop Pro 4300 that have similarly located IO that could probably fit the MS225 chasis. If I could just buy the motherboard of a 400 G1, I could probably install a haswell or broadwell CPU, but it's only $280 to buy the whole computer, so It's honestly not even worth it. Plus I think I can trade this AIO to a friend for his similarly spec'd tower that will allow for more upgrades. Think I'm gonna let this one go.
