It is, to say the least, and intimidating looking projector, larger than even the BenQ, Sony, and JVC entries, though smaller than most 3 chip DLP home theater projectors.
The projector has filters that recommend cleaning every 500 hours. They recommend using a small vacuum cleaner placed up against the vents to pull out the dust.
Since it has an LED light source rated 20,000 hours, there is no lamp door issue to consider. Many projectors must be unmounted to change their lamps (if ceiling mounted). Since it is unlikely that even the heaviest users will own the projector longer than the light source lasts, it's a non-issue.
The H9080FD comes with a cable cover to keep things nice and neat. Here is an image of the back of the projector, and a second one, with the cable cover installed.
The Vivitek logo pops out to pull cables through, but it also looks like you can pull the cables through the bottom of the cover.
