Check How to Handle Remote Windows PC, VM Sessions and VPS?
IMHO buying a windows mini pc with 5 year upgradable or just a budget version (convert to Linux machine later, self host open source software) is a better investment.
Use HDMI dummy, no need to buy a monitor. Setup once, let it run 24/7, like a VPS.
You get more performance and automation reliability because of higher cpu, ram and storage.
Just my 2 cents.
