Why do you have wires coming from the outside thru the window?
Keyboard, display, mouse, outdoor temp sensor, network cable etc...
If they could only make all those wireless...oh wait.
Wifi is unreliable. You can't VNC / teamviewer / remote desktop into a machine that has a wifi adapter that's deciding not to auto-reconnect. For this reason all of my primecoin miners ( 8 ) are hard-wired on 100/1000.
Also if something happens during POST or boot up, or a hang/wait on shutdown, and you dont have KVM connected, then you're screwed.
(Wireless KVM systems are in my experience: annoying, poor quality, buggy, laggy, and expensive).
