Questions about Corsair Carbide 678C

Is it possible to remove the 4 HDD slots that are inside the enclosure, or are they permanently mounted?

Hello Are screws included?

Unfortunately, the enclosure only comes with two HDD covers. Can I buy them as accessories from Galaxus? So this one, CC-8900353 https://www.corsair.com/de/de/Kategorien/Produkte/Zubeh%C3%B6r-%7C-Teile/PC-Komponenten/Geh%C3%A4use/Carbide-678C-HDD-Access-Cover%2C-Black/p/CC-8900353

I would like to mount my graphics card vertically, the enclosure is designed for this, but it does not come with any mounting material. Is it possible to buy them from Digitec?

On one of the pictures it has a control for the fans. Can these be controlled via the icue software as with the Commander, the basic requirement is that the components are all from Corsair and support the software?

Has this product never been bought before or for what reason does it not have a rating yet? Makes me a little unsure about whether I should buy it.

Why does it say that 2 fans are included, but you can clearly see that there are three?
