The device you are looking for is called a KVM Extender
It lets you have a Monitor(the 'Video' in KVM), Keyboard and Mouse. And the Computer can be put at a distance with a cable. It's also good if your computer is noisy - you can shut it away.
You may also want a KVM Switch, that lets you have one Monitor, keyboard and mouse, and multiple computers.

Comp --- \ KVM Switch -> KVM Extender------> Monitor, Keyboard,Mouse
Comp --- /
then you have both the ability to switch between your computers, but to do so seated at a distance from them.
FYI- There are other variations of KVM that are useful. A Reverse KVM switch, lets you have multiple 'consoles' (keyboard and mice and video/monitor) and one computer. So you could sit at location A or B or C, to access a computer at location C.
And for your further info, another called synergy works as software, lets you have one Keyboard Mouse , multiple Computer, multiple monitors. I used it years ago. And windows lets you have one KMC multiple V.

2I could imagine that with your high-end gaming requirement you would be better off with a long HDMI/DVI/DP Cable and a wireless Keyboard/Mouse hooked up to three PCs at a separate location in the house (plus audio). For office applications it is done with more or less thin clients and so called "Terminal Servers". That approach can easily host 10+ user sessions but not for high-end gaming. Maybe specify the distance you are talking about, to allow for people to suggest alternatives. – TheUser1024 – 2014-06-01T10:37:42.807
possible duplicate of Can two users simultaneously share one pc, also maybe check out Does Microsoft MultiPoint Server 2011 support hardware 3D acceleration and dual-head? for some ideas regarding gaming.
