Hi ! I am a german modder and i will show you many pics of my case. The black material is plastic (PE). The other plexiglass, alu ... I have planed and designed with AutoSketch. At work, i can build/produce this things on cnc-machines. Now the pictures sorry for my bad english more picture coming soon...
Darn right you must build! Keep it up, I'm excited to see what those tubes of whatever end up being used for, and how they're used. Word of caution though, your large aluminum waterblock and the copper (looks like a cuplex?) block is mixing metals, bad idea. Make sure you run an anti-corrosive agent (like antifreeze or Hyperlube supercoolant) or you'll be sorry!
Now THAT'S how a scratch built case should be done! Obviously there's been some serious planning and design done here Every piece so far looks amazing.
I love the hdd waterblocks, truely an origonal idea The case is shaping up nicely, I love your res idea, although are you sure you need all that water, it's going to be heavy I'm going to keep an eye on this one
