I have the original HQ16 which is larger. It just fits into an alcove in my room on 3 sides. I do not like pantos so never have to get behind it. I don't need to get by the ends either. If it needs service you are just taking the machine part. I have had this set up for at least 8 years and it has worked out just fine for me.
Not sure if this is a similar set up???
