Well, *where* it was purchased is of great import. There were thousands or tens of thousands of small computer builders who stuck labels on generic cases. Maybe hundreds of thousands.

That area is probably also your best bet for finding one. I have a couple of 90s cases from local builders here.

The closest I can find is an advert for a later model published in the Guardian in 1998 - https://www.newspapers.com/newspage/260394022/ it seems at that time the company was exclusively mail order through adverts placed in newspapers or catalogues.

I think the model I had was advertised in the British newspaper The Daily Mail, probably sometime in February or March of 1996. As mentioned the case was actually die-embossed with the letters MJN. I suspect they were manufacturing their own cases but from the looks of the advert above, they were using off the shelf parts internally. Although the company didn't stand the test of time, they were a medium sized UK company that did produce a fair number of OEM machines, under a variety of brands. Unfortunately very little seems to have survived about them though - since it doesnt look like any of their product catalogues have survived and made it onto the internet.

Little update; I have sucessfully managed to track down an advert for the PC... It was slightly later than I thought (December 1996 rather than March/April). I spoke to my parents who said the attraction of this particular PC was that it included everything (screen/PC/keyboard/mouse + ton of software) for a fairly low price and came set up out of the box with the OS/drivers all installed, which at the time was not necessarily always the case. In those days my father was very familiar with Apple computers but would not have used a Windows PC, so I imagine the idea of not having to set it up appealed to him!

From what I recall I had the P166+ model with the 15" SVGA screen, and I believe a 28K modem. We then added an Orchid Righteous 3D II, I think after about 6-12 months, sometime in 97/98.
