ThunderData is a small OEM manufacturer in Guangdong, China.

They also offer it in a nicer case to other manufacturers, still with exact same circuits and clock. Here it is as the Nuprime Omnia SW-8 at €499
“NuPrime licenses Omnia SW-8 from Thunder Data Co. Ltd., maker of Bonn N8. Omnia SW-8 differs from Bonn N8 with an upgraded low noise power supply and aluminum chassis”

And then as here it is branded by English Electric as the 8Switch
£450 (note currency change & difference) but ships with a 0.75m C-Stream cable worth £40.
