I'm getting a bad back whilst using my laptop sat at my desk so I've decided to get a small PC and connect it to my 42" 4K TV. I figured if I'm not leaning over a laptop i'll fare a little better.
 
	 
 
	I wanted to ask if anyone can suggest the cheapest way possible for me to get a desktop PC which has reasonable spec and will do the following:
 
	 
 
	- Have HDMI out and cope with a 4k resolution
 
	- Can run photoshop / office applications, normal stuff
 
	- Being able to play some old games like CS:GO or BFME2 etc would be great but not really necessary.
 
	 
 
	I have a pretty low budget, around £300, which isn't going to buy much but I want to get as much as possible for my money.
 
	 
 
	Could anyone help me search for something sufficient for my needs? I'm hitting a blank on Amazon at the moment.
