Competitive Products are:

3Com: SuperStack 3 Switch 3300, 3900, and 9300
HP: ProCurve 2524, 2424M, 4000, 8000  (also a very good switch)
Nortel: BayStack 450T Switches

                        ^^^^^^^^^^^^^^^^^^ we use Thermaltake Volcano 6cu,
7,000rpm

only vendors qualified.

Zippy makes a 435w

I believe the power supply is inadequate. After looking at Rackmountpro's
web site noticed they have a dual Tyan offering and also use a Zippy
P2U6435P-AMD PS.  Does Rackmountpro support a 300w on a dual AMD?

Might want to take a look at Ci-Design RS2100 with a Zippy P2U6435P-AMD PS
its been qualified for the Tyan dual AMD offerings.  Another chassis
offering is from AIC, again designed specifically for the Tyan dual AMD.

** Might want to add in an additional chassis cooling fan.  This resides in
a open PCI slot and will pull the air warm through the back of the case
reducing internal heat. **

Cheers,
