Highscreen / Vobis were huge in Germany and Austria. They kinda made computers accessible to everyday people. Back in those days, there were a lot of "hardcore" computer shops run by "hardcore" shop owners, which confused a lot of everyday people.
Vobis understood that and "unconfused" the masses by using simple language, appealing marketing and advertising and having clean / accessible stores in shopping malls.
They also serviced their own machines, so it was a one-stop-shop for people, and back in those days this was really important, because the industry had a lot of shady shops that took your money and sold you something overclocked, something fake, or something not compatible with each other.
With Vobis you got this OEM sense of "it just works", without having to pay as much.
That tower Amigaz has is a full size Colani tower. Luigi Colani is a designer, who likes things to be roundish and thus, ergonomic. Vobis teamed up with him and they launched a Colani themed desktop and full tower case. They were quite popular, although some people can't stand the look of them.
There are also other Colani accessories, such as joysticks and mice. It all looks very 60s/70s.
My first 386 was a Vobis. It had the design before Colani and a friend of mine bought the tower version.
The parts inside were a "surprise package". Vobis sourced components from Asia and placed massive orders. Despite this, it's possible that a similar configured machine has a different mainboard and video card.
They often didn't mention the brand of HDD or video card, and back in those days that wasn't important. They also didn't mention the brand of the processor, at least during the 386 days, because my 386DX-33 had a AMD DX-40 CPU clocked at 33.
You also got a CRT Monitor (Highscreen branded) and a very generous software compilation. In my case you got Windows 3.1 and Dos 5.0. All with very good, printed, documentation. There was usually something like PC tools or some other software bundled.
Vobis did try new things. For example the did bundle machines with OS/2 for a while and they also had some machines with RISC processors. I think something with "Alpha" in the name, can't remember.
They also had Highscreen branded accessories, such as scanners and Sound Blaster clones. All these items were simply rebranded, but to the customer this didn't matter. They knew it would work well and Vobis did offer support as well.
EDIT:
I finally got around to scanning in some pages from the "Highscreen Highlights" magazine, which I recently purchased from eBay Germany. Nobody else was bidding!
This magazine is pretty much from around the time I got my 386DX-33. So I was hoping there was an ad in this magazine, and I was lucky. It has the EXACT machine which I had as a kid. Same CRT, same yellow font on the front sticker, same software bundle.
Here are the pages:
PS: W7 paint sucks at scaling an image down and saving it as JPEG. The file ends up quite large, but looks worse. I then tried GIMP and got much better results...
