I interview candidates for engineering roles in my part of the CS. As others have suggested, I won't really care where you got your degree from, though I might be more interested if it's from the OU as that says a lot of positive things about the candidate.
I'll be interested interested in whether your quals match the role requirements, what modules you did as well as the experience/skills you bring to the table and any extra hobbies or activities you do that I might be able to pick skills and competencies from (you'd be surprised how many professional skill sets go into building a PC, restoring a car or modernising your house uses).
You put the best effort you can into a degree that suits your career goals at the uni that appeals to you in the city/town that gives you the best university adventure experience possible...... and you will do just fine and have no reason to feel regrets.
My first Uni adventure was at Exeter btw and I've long been fond o the city and Uni. Since then, I've been to Plymouth, Cranfield and the OU and enjoyed my time at all of them. It's a nice city, though a bit expensive sometimes but it's a good place to be.
All the best and if there's any Qs I can answer, let me know.
