$15 power supplies of any variety are invariably garbage...  there are
plenty of 300W power supplies in the $30-$35 range from larger taiwanese
manufacturers that put out 30A on the 5V wire.  But then, the price diff
between 300 and 350W is often $5, so go with the higher wattage.

An excellent Athlon/AthlonXP/AthlonMP cooler is the Dynatron DC1206BM-L,
it measures 60x60mm (horizontally) and uses a unique micro-fin design.
I've had very good results with it on the 1.53GHz Palomino core CPUs.
This HSF costs around $20 each.  URL:

I know it's possible to run dual Athlon-C (Thunderbird) 1.4GHz CPUs on the
Tyan S2460, but it's not adviseable unless your budget is really limited.
The Palominos (AthlonMP/AthlonXP) perform at least 15% better in many
FPU-intensive tasks.
