I would put the subwoofer outside of your cabinet. Think about it. A subwoofers send non-directional vibration out at a low frequency.   Vibration is bad for Monitors and computers. I spend too much money on my arcade PC to place it by my subwoofer.

You don'y play real arcade much???  Man, they get a beating and shaking of their life!  That's why arcade monitors have that roll cage around them.

Thanks for the responses guys.

I was originally thinking of having the sub box (me standing in front of cab) with the speaker facing forward, port on the left up against the left side of the cab.  The I thought I could remove the left side panel of the sub box, cut the port hole in the cab and mount the box hard up against the left side.  This would improve the sound coming out of the cab.

Would this help the problem of vibrating the harddrive, monitor? Or is it still affected by the the speaker movement.

I will have to check how much the sub vibrates, I know I can feel the bass, then I could see.  I have felt there is a lot of air moving through the port so I thought it would be best to have that push outside air.

Some more thinking required I guess.

I believe bass is mostly transmitted thru vibration, not direct movement of air.  Really top-line subs actually have spikes on the bottom so they make contact with the floor thru the carpet!  Guys drive down my street with woofers in the trunk, and I can FEEL it 3 floors above!  I think you should be able to just mount it inside the cab without drilling a hole in the side, and still hear and feel the bass.  Just don't block the port so it doesn't hinder movement of the speaker cone.  I think you're way overthinking this...

HeadRusch:
Subwoofers are a very tricky item to place.  If you've ever set up a home theatre using a Sound Pressure Level meter, you'll know that where you place and point a subwoofer can have a dramatic effect on the sound it makes.

Too far away from a wall and it sounds weak, too close and it sounds boomy.  PS: The reason for spikes on some subwoofers is not to touch the floor, but rather to prevent the cabinet of the subwoofer from contacting a carpet, which can dramatically change the sound of the sub.....same rule applies to floor standing speakers.

Anyhow, the Z560 sub makes a *TON* of power.  I mean, it might not be Home Theatre quality, but as far as power output it is a monster for JUST a PC soundsystem.......you'll get better sound outside the cab, since the air is going to move in the direction the woofer is facing (the side port is for air "behind" the diaphram to escape".....the sound comes from both openings......however trappingit inside wont give you much less "oompgh"...it just might make the sound "boomier".

Yeah, I built my sub for my home theater.  I'v ebeen moving it around the living room seeing where the best spot it.  near the bay window is it boomy.  Where it is now the sound is very precise but a little quite.

I put the cone feet on too.  having a complete side of the box touching the floor changed how the sound reflects off of it.  

My next sub will be more powerful.  I want to install it in a sano tube because I hear that is the best for sound.  Right now I have an 80w amp and the 10" Titan driver from partsexpress.com.
