Don't get cases only because they look cool. Make sure your components fit, good airflow, easy cable management etc. I could recommend you some very good cases if you tell me how much you are willing to spend on a new case.
ugly ? what do you think is the "best performance " best looking case " for £60
They are ugly in my opinion. If you think they are cool, and you are happy with it, then keep it and enjoy it. It's personal preference really, other than looks in my opinion, it's not a bad case from what I can see. And anyways you said it yourself "It started looking a bit ugly" xD GL
