I wouldn't be so hasty to put c200 into the grave :-)
I often wander how often people speak about things they don't understand and blame in that case Apple that it's to expensive. Please try to build first similar spec. DELL workstation. I've tried. Entry level iMac pro vs dell - dell is 5650$ without screen at all. Pro stuff is expensive because it just work. You can build cheaper custom hackintosh or PC but it will always be, well sort of Frankenstein. If you need it to be reliable just buy Dell or iMac Pro. To be frank I'm the owner of hackintosh and it's really good, but I sent hundreds of hours to make it work, hours that I can spend earning money.
First of all I keep my finges crossed for the author and his film, but I have some problem with the first sentence of this article (Here's how to make your movie look like a sci-fi masterpiece). You don't want to your film look like masterpiece but to be a masterpiece. This is major difference in thinking. You can obiously use the knowledge and inspire from those big titles, but you need to find your own language there. If you just concentrate to look like bladerunner you will never think out of the box. Think about mood & story and try to find your own ideas and maybe, just maybe somwhere in the future someone will give your film as example of extraordinary cinematography. Jus my two cents.
