Chaotic Neutral
I was very lucky to snag myself the last ever Gigatron (TTL based microcomputer - made almost entirely from components available back in the 1970s) complete with case (there are still kits without the case available). Unfortunately it has a chip in the front, but matters not. I'm looking forward to assembling it, when I have some time. The manual is also fantastic.
Not only that, it's now fully open source (including the hardware).

There have been assembly videos and reviews from 8-Bit Guy, Ben Heck and EEVBlog (so I suspect a good proportion of you will have heard of it before), although some of those videos were made around the time of the first ROM and seem a little unfair now.
