The k version CPU has an unlocked clock, so you may overclock the CPU speed... if you do not plan to overclock, you don't need the more expensive k model

I went through this a year or so ago.
It seemed easier and safer in the long run to just have it built and tested for me, so I contacted Eric at ADK. He hangs out around here, mostly in the hardware forum.
I did a lot of research and read all kinds of posts, and read all kinds of articles. I thought I had the final plan and just checked with Eric so see how much he wanted to build and test it. I checked with other companies too, but Eric challenged my assumptions instead of just agreeing to build what I thought I wanted.
Well, let's just say I ended up with a different processor, a different hard drive configuration, different memory, a different size SSD, different cooling, and so on. Let's also say that I am quite happy with what I bought and have no problems editing anything I throw at it. Some people make their living knowing this stuff backwards and forwards, and the folks at ADK fall into that category. Yes it costs a bit extra to get it built and tested, but I believe it was worth it.
Your budget will not allow you to have as many hard drives as I have, nor possibly as much memory. On the other hand, the processor I have is probably a lot cheaper now. And hard drives are cheaper per terabyte than they were then, etc. I suggest you tell him your budget and see how much he can cram into the system at that price.
If you really want to build it yourself, I have seen good results from people using the info at Videoguys.com. The DIY 9.5 can probably be had for a little bit less now too.
Or, as John suggests, you can do an awful lot of reading and see what happens.
Thanks, it is a daunting task, I am reading on ADK, thanks!!
Thank you very much!! I love the video that Dave posted.
