recommended vendor for AMD64 machines?

[James Ralston <qralston+ml.redhat-amd64-list@xxxxxxxxxxxxxx>]

This is slightly off-topic, but probably the correct audience for this
question...

I'm looking to purchase an AMD64 server, to evaluate GinGin64.  I'm
looking for these features:

    1.  No smaller than a 2U case.
    2.  SCSI (not IDE) disks.
    3.  Price in the $2,000 to $3,000 (USD) range.

(I could deal with a cramped 1U case if necessary, but I *really*
don't want IDE disks, as I want a realistic performance comparison
with our existing Dell PowerEdge servers.)

Any recommendations?  (Any dis-recommendations?)

Thanks,
