Work implemented a new restrictions and I'm absolutely tired of having this machine on my desk. It needs to be connected to VPN at all times and cannot be RDP/VNC into it.

I'm looking for under $400
Accessed via local network
Low latency at 1080p (50hz or higher)
Can be accessed either like RDP or in a web browser (like Chrome remote desktop)

Any recommendations or is piKVM really my best option?
