  OK -- I finally finished it yesterday.  I'm not a web guy -- I 
handle the equipment, not the content -- so I just threw some images 
up in my space.  I'll make a detailed page... eventually.  I need 
some practice with the digital camera and a room with some light, and 
some time to poke around with HTML.  (The default page that's there 
was done by a friend about 10 or 11 years ago, to try to force me to 
put up something of my own.  I've been too lazy to change it -- as I 
said, it's only been 10 years.)
  Some of these are pretty large, and the DSL's pretty slow upstream. 
 The last two are the finished product.

Now it's a bit more than 2U.  I'm a bit disappointed with its 
performance -- space constraints and Juniper's odd decision to use 
3.125" centers rather than (Intel Socket T standard) 72mm limited my 
choice of heat sink somewhat (it's a Swiftech MCX603-V adapted to the 
Juniper's mounting hardware), and the power supply is the source of a 
surprising amount of noise and vibration.  Even so, the system 
performs well enough:

SSG550-> get chassis
Chassis Environment:
  Power Supply: Good
  CPU Temperature: 123'F ( 51'C)
  System Temperature:  80'F ( 27'C)
[...]

...and it's not as though I expected the Rotron Major to be quiet 
when pulling through a restrictive filter in any case.  (The knob in 
the corner is the speed control; I limited the range somewhat so 
curious folks can't cut the fan speed too much.)  So it's a qualified 
success: It equals stock cooling performance at a minimum, it's 
quieter, and it cleans the whole room while remaining sparkly clean 
inside (no joke).  Oh -- as a baseline, the room A/C thinks the 
ambient temperature is 78F, while my APC UPS environmental monitor 
thinks it's 86F; the reality seems to be somewhere in between.
  Y'all have to admit -- it looks pretty silly.  Now I need to get 
off my backside and put this up in place of my old 7140.
