hi diego...

- for fun... real prices of parts is shown below too...

these amd'based 1U servers is tough to build..
major heat flow and air circulation problem...

amd chips and intel chips are different height
when sitting on their respective motherboards
and different heatsinks...et...etc..

there are some that have 1U based amd's
( but probably not cheap???

-- you also have a problem with availability of a
   amd motherboard w/ onboard NIC and onboard svga

- we can probably help with some experimental 1Us
  w/ hard-to-find amd fans for 1U

- the 400W power supply issue is typically based for worst cast
	- you need to count and measure power consuption
	for startup and for normal computations

	- power supplys can support extra power spikes
	for a short time period for those spikes in computations
	( its NOT steady state )

== air flow and cooling should be the primary issues
==	2U chassis is your best bet if space is not an issue

some discounts.... is probably likely...??? depending on vendor
