The Nebula looks nice.
It seems new, because I can't find many build pictures on the net.
Only pictures from the Computex 2013
Few thoughts, from what I read on their website.
Alumnium side panel with a quick release: it looks great, but I would be cautious. If it's just kept in place by some little opening mechanism, it might vibrate a lot. I prefer to take off 6 screws, once a year, but keep a steady non-vibrating case.
But maybe they did it well.
If you go with picoPSU,take a tower cooler (HR-02 Macho or Mugen 4, as recommended by many on this forum and from the reviews)
If you go with PSU, I would really look for modular.
Did you see the crazy bunch of cable on the picture.
Finaly, I don't know this brand. It is well known for quality? Is it cheap or expensive?
Is it as good as Fractal Design, Lian Li and SilverStone?
Back to the picture from Computex, if I was selling a case, I would never present a so messy cable management.
I would have gone for a modular PSU and clean look. Or even, I would have cut all un-necessary cables from the PSU, to make it as neat as possible.
Again, I don't know this manufacturer. It's just my thoughts, after what I see on the web.
85€ in Europe. It seems a bit expensive, if it's not (recognised) high quality case.
You are not planning a GPU, which is good in this box.
Looking at this other picture, you can see the GPU fan will be directly on the side panel, which doenst have any ventilation holes.
I guess, it doesnt allow a good airflow.
