Hello,

I am looking to spend $10k on a computer cluster, or single computer (if it's possible)

Basically I want the most r9 280x's possible with $10k, whether that be 10 systems or 1

How can we get the most r9 280x's into the cheapest build and make sure everything needed to mine on it is compatible.

Let me know your build suggestions, and I will give you a shout out in a video if I use your build.

First of all, ASIC have plowed GPU mining into dust. You'll be losing thousands of dollars on this build unless you start mining ethereum.
For a build like this, you'll want a motherboard that has as many slots for PCI as possible, with a good cpu like a X4 or G3220.  There'll be implications with PCI slots for the cheapest mobos, but one for example could be the AMD ones.

The cheapest ones may only have PCI which will bottleneck sometimes,  but for mining this is okay if you want a low price.

I am going to be mining ethereum, and yeah I am looking for what ever is the most cost effective way to get hash rate with $10k

Are you up to date with ethereum's plan to switch on a PoS-like system to replace mining?

No, but I thank you for informing me on it.

What is it, and how does it work? And it will it really be implemented?

why?  The r9 280 will be out of date by June 30th.

The r9 480  will do 26-30 mh  with 100 watts less power.

Building eth ris is not rocket science.  Trying to go past 6 gpus per mobo is pretty much a waste of time and effort.  Asrock's 6 gpu board with risers  is about the densest setup.
