Help with さすが大学に行っただけのことはある


It's an example sentence from tangorin.com, I wanted to know some sentence
examples for さすが. One sentence I found is completely confusing for me, I can't
logically translate the sentence to the original translation below:

> 彼は **さすが** 大学に **行っただけのことはある** 。  
>  He didn't go to college for nothing.

The really confusing part is especially the rear 行っただけのことはある. I know that
simply said ことがある means 'to have done something', concluding that (in my mind)
the translation would be something like:

> This guy, as one would expect, he _did_ really go to university [ _only_ for
> the sake of going to the university].

Giving you the image that this guy is some bum instead of the right
translation which gives you the image that this guy is actually something.

But, as you can see, my translation is nowhere near the original (right)
translation, also due to my level of Japanese being only somewhere around B2.

> さすがは～だけあって （just） as expected of （just） as you'd expect of just as one would
> expect from just like

From my understanding, It's basically saying " **It was no surprise that he
went to a University** ". The sentence puts emphasis on it not being much of a
surprise, that the person speaking didn't expect anything less the man in the
sentence.

In this example the だけのことはある should put even more emphasis on the fact that
it's little surprise that he went to a University. Probably means that the
person is quite smart.
