For the last couple of years, Dell's foray into the small-form-factor desktop market was its successful mini-tower (with the emphasis on "mini") Studio Hybrid. But with Dell's latest small-form-factor entry, the Inspiron Zino HD, out goes the vertical mini-tower and in comes the horizontal square--7.8-inches wide by 7.8-inches deep to be exact, and a mere 3.4-inches tall. Like the Studio Hybrid (which Dell still sells), the Inspiron Zino HD (a.k.a. the Inspiron 400) is a solid little machine, with decent mainstream performance, and geared towards budget-minded consumers. Similar to how you could change the Studio Hybrid's looks by swapping out different-colored sleeves, the Inspiron Zino HD can switch personality with the snap of new color or pattern lid. Of course, other than the default "Piano Black" lid, you'll have to pay extra for any of the Inspiron Zino HD's other color ($15 each) or pattern ($30) lids. And with a starting price of $249, the Inspiron Zino HD can give any number of nettop PCs a run for their money.
