In case you guys missed it about two weeks ago the seller piospartslap on
ebay.de listed the Fujitsu Futro S740 (J4105, 8GB RAM, 16 GB SSD) for 62€. Offers of 50€ were accepted and a Promocode "
PROMORESTORE22" could be applied for a total of 45,90€. They still have listings, give it a try maybe it still works. They also have listings for lots of 10.
I know 46€ is 50% than the 30€ for a S920, but here you get a much newer CPU with more performance in a similar package. Just might suite your needs better.
Just FYI, I'm
not affiliated with the store in any way.
Cheers!
