Windows 10 is a plus at this time
SD and DVD drive are a plus
Here's a link to Acer for better info than eBay - https://www.acer.com/ac/en/US/con....BH7AA.00
Yes, the 512GB storage is SSD of some kind, either SATA or NVMe.

A Zalman fan running at the same speed is smooth whereas this Cooler Master fan at full speed actually bounces around on my desk. It's not clear if the fan is possibly unbalanced, the drive circuitry, or just the way the motor is wound. Reducing the voltage has no effect on the vibration.
So a better quality fan may solve the issue.
If anyone rewinds the fan motor for a lower kV or different termination I would be interested in the results.
I wonder if removing the shroud would help with the vibration any. Most Intel OEM fans don't have a shroud. Hmmm, kind of a destructive test for something that might not do anything at all...

Edit:
I should be more clear by what I meant. There are no BIOS settings related to bifurcation but there is a possibility it supports automatic configuration. Unfortunately I have no way to test it at this time.

The way the mounts are done on the Be Quiet fan it would hit the heatsink mounting studs. You might be able to cut the fan mounts off on one side but...
The Be Quiet fan probably doesn't move enough air. Because of the small heatsink in a case with no airflow the fan needs to be able to run pretty fast. I think the stock fan is like 4700 RPM max (though it may not need all of that). The Be Quiet fan is 1900 RPM max.
It's possible to run at a high speed and be smooth. It will be loud because of the air moving but at least it won't vibrate. To actually be silent/quiet you would need to replace both the heatsink with a better, bigger one and with a lower RPM fan. Currently I'm just trying to solve the vibration problem.
