The Apple Store takes up to $150 off a selection of factory-refurbished Apple Mac mini desktops and servers, with prices starting at $509. With free shipping, that's tied with our mention from three weeks ago as the best discount we've seen since Black Friday (when we saw them from $469) and puts each at the best price we've seen for these models with an Apple warranty. A 1-year warranty applies to each, the same as new systems. Some best bets:

• Refurb Apple Mac mini MD387LL/A Intel Core i5 Dual 2.5GHz Desktop (pictured) for $509
• refurb Apple Mac mini MD389LL/A Intel Core i7 Quad 2.3GHz w/ OS X Server for $849
