Really for a one man shop likely a G0442 would be a better option at only $500 more than the G0673. No need for any add on cost for a cyclone and an 8" trunk should be sufficient for your needs. It's what I put in my shop. I built an external closet for mine to reduce noise but I am using the filters and not venting outside to keep my shop moisture content low in the summer and not lose heat in the winter. It is a really good value for a 5HP single phase cyclone DC.
