Bag to fit Tower

[stingray0147]

I know this isn't quite the right place to put this, but i couldnt think where else i could.

I am currently looking at building my first computer, i know all the components i want now, but i would like some help finding a bag for the tower that i can use to take as carry on luggage. I am at university in england and my parents live in france, i want to be able to take only the tower with me but i have so far had no luck in finding anything.

This is the case that i have decided to go for:
Fractal Design Core 1000 micro ATX mini tower

The only bag i have found is the Thermaltake eSports Bag, but it has compartments in it for basically anything except a tower. I was wondering if i removed the compartments whether or not this would serve my purpose.

If there is any help you can give me, i would appreciate it greatly. Also if there you're interested, this is the build i am planning on going for:

That's a small enough case you could throw it in a tote bag, but why do you need a bag?

I have a bitfenix prodigy, and take it as a carry on a fair bit - I just throw it in the overhead bin nestled in tight between luggage.
