Cheap HTPC

Hello world, I am asking for assistance in coming up with a cheap HTPC that will be hooked up to a 4k tv I am a Intel and Nvidea fanboy however if it means price savings I will go for anyting reliable. 

My budget is as cheap as possible however while still having a fairly decent amount of memory and the ability to play movies in 4k. If the case is windowed I would like color matched components with preference to black/blue however anything is ok. Windowless cases are ok too though, this build is all about as low of a price as possible while having reasonable performance for a HTPC. 

This is my second build, I do not intend to game or video edit on it.

As for parts I have no idea where to begin thus I come to you for help

 Copy and paste from another site, but the information is solid.

Here are the minimum system requirements for PC and Mac for 4K playback based on processor and graphics chip manufacturer's websites. 

Integrated Graphics solutions that support 4K external displays (8GB RAM recommended with integrated graphics solutions):

  • 4th generation Intel® Core™ processor family (Intel Haswell based CPUs) - (Intel® Iris™ Pro Graphics 5200 / Intel® Iris™ Graphics 5100, Intel® HD Graphics 5000 / 4600 / 4400 / 4200) 
  • AMD A10-7800 APU 

Discrete Graphics cards that support 4K external displays:

    • Nvidia GeForce 
      • GeForce® GTX™ 970
      • GeForce® GTX™ 980
      • GeForce® GTX™ TITAN Z
      • GeForce® GTX™ TITAN Black
      • GeForce® GTX™ TITAN 
      • GeForce® GTX™ 780 & 780 Ti
      • GeForce® GTX™ 770
      • GeForce® GTX™ 760 & 760 Ti
      • GeForce® GTX™ 750 & 750 Ti
      • GeForce® GTX™ 690, 680, 670, 660, 660 Ti, 650, 650 Ti BOOST, 650 Ti
    • AMD Radeon™ HD 7000 Series or better 

Other things to consider:

  • You need to have a monitor which is capable of playing back 4K video if you want to properly play 4K.
  • Even if your computer meets the requirements, you may find that 4K video plays back choppy.  This is due to the immense processing power required to play 4K.
