So the experts in the Swedish Facebook Group "Retrodatorer
säljes/köpes/bytes (C64, ZX, MSX, ATARI, AMIGA mfl)" seem positive and a
couple of them have seen these before and there are even some owners.
it's an A3400 and every detail match so far. Some A3400 had Amiga 3400
printed on a white/beige front panel, others had a black front with just
Amiga printed one like this. The motherboards say A4000 Revision 1 and
the fact this got the 68020 and 68030 CPU on the same card is another sign.

So now I feel a responsibility to restore this beast. The battery just
came out (yes the classic issue I wish I had known that 17 years ago
before putting it in a box) and there is some serious corrosion damage,
I hope it's not as bad and repairable. Have done a quick vinegar soaking
and cleaned up with a toothbrush, alcohol and compressed air (the tip I
got).
Still a pro will have to lift some chips and and do the proper
assessment or repairs. Hopefully proceed with a capacitor update and get
it running. AFAIK it worked before going into the box.
Any recommendations of a Amiga/A4000 hardware guy who can do this?
Either way I will bring this machine to World of Commodore.

Added another photo. Close-up of the daughter board.
It does say A2400/A3400

However it's also labelled "A4000" so not sure if it's an A3400. Commodore tended to change model# designations a lot. It does seem to match the A3400 described here:

Exciting!
In the 90's I had a game development company in Sweden and some of the
artists preferred working on Amiga. Electronic Arts England sent me some
decommissioned Amigas. One A3000 and this one.
Then they went into a box for almost 20 years. They got shipped to
Canada with some other stuff some years ago and have been sitting in the
box at my cottage until the other week.
It turns out one is an Amiga 4000 pre-production model. One guy thinks
it's an A3400.
Perhaps you guys can shed more light on the matter. I'm willing to take
more pictures if needed.
There is some old dust, especially on the CPU board contact. It looks
nastier than it is.
