Since my computer died spectacularly a while ago, I ordered a new power supply for it. Fry's had a great deal:
Power supply: $28.00
Mail-in Rebate: $28.00
3-day shipping: Free with deal: $0.00
Total cost of power supply:
$2.30 Californian GST.
And now, my computer (sort-of) works again. It won't play Warcraft, though.
