Not an answer but another idea for jogging your memory. I don’t know what PC magazines were popular in Germany, uhh well ever, but it’s not too hard to find archived copies of popular magazines here in the US from that time.

Here is a random copy of PC Magazine from some month in 2006.I didn’t see any PCs that matched your rendering, but there was an Acer Aspire that I had completely forgotten about.
