The DW611 has vents in the bottom of the spindle that would blow the dust away from the path of the bit. I just think keeping the vacuum on all the time would defeat the purpose of the enclosure. But I am curious about the belts and track, maybe we need some accordion boots like I saw in a thread.
I've run without dust control both with the machine inside and outside of the enclosure. In both cases I would not recommend running the machine without some sort of dust control unless you'd be using something like the accordion boots like you've mentioned. Otherwise, especially when inside the enclosure, dust gets caked in on the makerslides and the v-wheels leading to missed steps and inaccurate cuts. This is amplified for very long jobs and for jobs cutting materials synonymous with crazy amounts of dust.
Also, not all spindles have their exhaust venting towards the bit, so if you want to keep the area clear around the bit for viewing purposes, dust collection is a must. (Or a separate blower pointed at the bit).
I'm not sure how running a vacuum defeats the purpose of a sound proofing enclosure exactly either. In my case, my vac runs about 66dBs where my spindle produces near 100dBs with the door open (60dBs with the door closed). 66dBs of sound is about the same as a normal conversation. I do have plans to enclose the vac at some point to, but more for aesthetics than anything else (even though it will end up dropping the dBs).
Even if you would strictly be using the enclosure for dust containment and were using accordion boots to protect the makerslides and v-wheels, I still see benefit in running active dust collection if you have the opportunity to do so. For example, airborne sawdust is highly flammable. When contained within a small enclosure with exposure to electrical devices such as the spindle and stepper motors (and if you're crazy enough, the controllers) then without dust control, I'd recommend reading the forum post on meeting the local fire department. Even with dust control, I keep a fire extinguisher handy (mounted directly to the enclosure) and never leave the CNC unattended during a job.
