I ran through what this would look like last night after I decided to put in a $20 offer on a SFF office PC and went "... oh shit what would I do with it". Thankfully, the offer was not accepted.
But it was too late.
There's no one I could even build this FOR right now for cost of parts. So I'm gonna walk through it here. Keep in mind this is a "I want to spend the LEAST amount of money possible" kind of setup and it's a little, ramshackle. You'll see.
Pricing and availability based on what's here in the US. Sorry.
After seeing this post from Plum I was inspired to actually do this. (BECAUSE ONE OF MY HARD DRIVES BLEW UP AND TOOK MY BEAUTIFUL MUSIC LIBRARY WITH IT)
And I am PLEASED to announce that it worked!
So now I'm gonna run down what I did and how I bodged this into happening. Then I'll tell you how much this cost me.
