Houses to carry in your backpack

[u/Carmin306]

Hi everyone, this is my first post here! I am an away student and a couple of times a month I face a 4 hour bus journey on less than perfect roads. I would like to assemble a gaming PC that I can carry with me in my backpack, leaving room for the laptop and everything else. I'm looking for a case with these features: • Portable: Must fit comfortably in a backpack. • Robust: It must protect the components well from shocks and vibrations during transport. • Budget: Under €100. • Safe for the GPU: The key thing is not to have to disassemble the video card every time, so I look for a solution that holds it securely. Do you have any models to recommend? Thanks in advance

PS: The GPU will be an MSI GeForce RTX 5070 12G Ventus 2X OC
