Look my friend,
The question you are asking yourself should not only be "what do employers think" but "how much will I learn and accomplish with the opportunities given to me." I know 100% that you will have more technical opportunities at a school with a thriving CS department. Student projects. Assisting in research. **These are what employers look for** Furthermore, your coursework will be of higher quality, your professors (mostly) will be more in tune with industry, etc.
Finally, recruiters DO care about whether they've heard of your CS department... I mean, my CS department is so linked with companies that I got interviews with all the great tech companies you hear about without even having to think much about it. They came to ME. Consider that.
Finally- I suggest a compromise. There are MANY good schools with a vibrant Liberal Arts college AND a fantastic CS department. University of Illinois and University of Michigan come to mind. If you want the Liberal Arts curriculum so much, why not choose one of those? They aren't Stanford or MIT, but trust me, employers in the midwest respect their curriculums.
