But what I'd really like is that to-scale case and put a small PC in it. Even if one does not care at all about its historic significance, the Cray-1 was one of the most visually appealing computers I have ever seen. Having a miniature version of it sitting on my desk would be extremely cool.
On a slightly larger scale, I will, eventually, in my infinite space time, have a full size wooden cray I in my rec room as a sitting couch. I have the carpentry skill and tools and structural experience to pull this off. For many years I have periodically worked on dimensioned drawings. My strategy revolves around making eleven identical 22.5 degree segments with a framework and panels mounted in slots and two "about half" segments and then bolting the column detail from one to the internal framework of the other. This makes it very easy to build and very easy to move (well, sure, 13 total segments and maybe 10 bolts each means a lot of wrench time when you move it, but no segment is individually too big for a person to move.)
To warn other people, this is a typical "large machine in a giant data center looks small, but it looks huge in a normal size house" kind of problem. Its about six and a half feet tall and about eight and a half feet across so its a rather substantial investment in space. Then again you can use the enclosed volume for storage. Essentially you have eleven small full height coat closets and under seat storage also.
I have a basement rec room / craft room / lab that runs the length of my house so it will be more or less in proportion other than height.
