Ienien77 you should find Gigabyte server resellers quite easily, for example, Scaleway has a lot of Gigabyte servers in their datacenters ;)
Some resellers: GIGABYTE Servers - Rack Server
I might sell a X10SDV-4C-7TP4F in the next coming weeks, complete in box, with original SAS cables, bundled with 4x8GB DDR4 2133MHz ECC Registered. I'm located in Paris, France, but I'm willing to ship it to Benelux.
I also have an original heatsink with fan from Supermicro in case you...
