Custom case ideas?

[JForce]

Hi all, new poster here as I've been thinking about this for at least a year, but haven't been able to nail down the idea - so figured I'd ask here as there's plenty of knowledgeable people

 

Whilst I've built my own PCs before and am pretty comfortable, I've spent the last year getting into amateur motorsport, which has gotten me into basic fabrication and engineering stuff.  This has reinforced my desire to make a custom case for my next PC.

What I mean is that I don't want to mod an existing case, I want to make one from scratch.  I also want to make it look like "something".  I've been thinking about an F1 engine, but think that could be too big and ungainly.  I also like the idea of something iconic from a sci-fi movie or tv show - I've thought about Orac (points if you get that reference), and there's plenty of HALs and the like - but I can't nail down an interesting looking, iconic "thing" that could be a funky case.  Autobox Matrix of Leadership is an idea I've toyed with, but it's a pretty weird shape (not that that's a problem), but it still hasn't "clicked" for me.   I am a child of the 80s/90s, so classic tv shows/films are the kind of things I have swirling in my head.  The BTTF Delorean, KITT, these are the kind of crazy tech that inspires me because, well, I'm still a small child in my mind.

 

So anyone got any interesting ideas, things that could be a funky case design?
