Good looking start, Would have to agree the slogan and logo on the top is a turn off for most people.
I think most people prefer a clean aesthetic, especially on the top and you can get away with a bit more on the back or side.
Also, I would say your "H" logo and text's design doesn't translate well to the enthusiast market, sort of like how I think the dolphin text between the arrow keys and home cluster is a bit out of place personally.
Lastly, I think externally the design is clean especially that base! Good luck with the buy hope you take peoples feedback about the logo and consider the change
