What about that 4th computer, Apple-looking, in the background on the 'printer table'..? Included as well ? His ad does only mention 3 computers it seems... Ask him ?
As for bidding, I have a feeling the 1000kr asking price is normally a starting point for UPwards bidding...
But then again, the old picture dates could be signs of this having been for sale earlier, and you might get it for say 500kr(or less!) if you convey that you're going to take good care of the stuff.
I got mine for free(!) after some messaging, but cost me 700kr in postage, for just a single machine+monitor+extras...!
Hence I assume you live close by, as the shipping cost would otherwise be quite painful... 🤣
(and high risk of damage, as their packing skills are normally on the level of a third-grader... sigh...)
- Now, IMHO, I think that what it is 'worth' on ebay is not that important (for this price range anyway), unless you actually plan to sell any of it later.
If you are genuinly interested in that hardware catagory (Apple/pre 486), and have a normal income/not unemployed etc, paying even 100-300kr more is not a deal breaker, seeing how rarely these items come up for sale in this region nowadays.
Vs the perils of buying and shipping these things via ebay(international) I mean.
For 250-350kr per (working) machine, it IS relatively cheap, I think.
In the end, it all comes down to your personal cost-benefit evaluation...
And these even seem to have been taken well care of(+ hard? to find extras), not dumpster finds or stored rusting in a barn for several years here.
(I've received stuff that had actual sheep wool inside the cabinets, and the smell....!).
PS:
the 67 year old seller seems to be 'CEO'(retired?) of "Off-Tech Data A/S", so these relics are probably remnants from that company. I.e. not much 'gaming-related' installed...
