Digikey carries "low impedance" electrolytics in typical values (like
1000uF/6.3V/0.09 ohm/105°C for 28 cents ea. in 10's) but they might be
bigger than the ones used on some mobos. EEU-FC0J102


True, but what they don't seem to have are the United ChemCon Oxi caps, which
is what the motherboards use. Oxicaps are about 1/10th the ESR of the
very best aluminum electrolytics.
