Simple Logo for a computer system

For my computer system i need a logo i can officially use on the web and as a sticker on my system.
So what should the logo look like?
Well it's a very potent system which can run multiple subsystems (symbole could be cell, the snake like create hydra or similar... representing the huge amount of it) . Those "virtual" systems share a common hardware.
The Logo shall represent the systems Name "Hydra" - as it has many subsystems - and shall be a quite simple one...
(Please see examples attached some logos created with a logo generator on the web).

Text:
Beside the Logo also it's name should be shown: "Hydra".
Somewhere below or surrounded by the text "A ShadowGhost.NET system"
Font: more technical, plain, not the standard ones but also not playful or so...
Color: Redish, blueish... simple... one color or two... not to many...
