Help me fit more stuff into my computer

[Hakolb]

Hello, I am thinking of purchasing a 2.5 SSD to hold my OS and programs. I currently have one 3.5 HDD installed.
My computer case does not support 2.5.
I saw some of those extra cases for HDDs that help you fit them into bigger slots.
The problem is that I hat to cut out my 3.5 slots to fit my gigantic video card.
Are there any cases that would let me fit a 2.5 SSD into a 5.25 slot?

Here's how it looks like:

Also, I am going to purchase a Samsung SSD 850 EVO 250GB SATA III MZ-75E250B
Is it a good SSD?

but 16 euros for a case is pretty expensive if you ask me...
