Inside the HP you'll find a well-organized interior ready for expansion by way of a standard PCI slot and three 1x PCI Express slots. The motherboard has room for two more memory sticks, the other two slots are occupied by the 2GB DIMMs, and there's plenty of space for another optical drive and hard drive. By comparison, the Asus Essentio CM5671-05 tells a similar story inside.
Around back, the HP Pavilion earns points for including DVI and VGA video ports, optical audio out, FireWire400, and 8 USB ports, but the Essentio offers the added benefit of HDMI for easy living room connections. Connected to a standard desktop monitor via a VGA cable, the p6510y ran full-screen video from sites like YouTube, Hulu, Vimeo, and Netflix without any hiccups and also played full 1080p HD movie trailers from Apple's Web site. Some of you might miss HDMI here, but if you're seriously planning to view your media on a TV in a living room, we much prefer a slim-tower system like the Gateway SX2840-01 (or the recently released follow-up, the SX2801-01e).
|HP Pavilion p6510y||Average watts per hour|
|Off (60 percent)||1.44|
|Sleep (10 percent)||2.93|
|Idle (25 percent)||66.57|
|Load (5 percent)||107.32|
|Annual energy cost||$29.43|
Out of the five comparison desktops we used in this chart, the HP Pavilion costs the most to power over the course of a year at $29.43. Compared with the $19.32 it takes to power the Asus Essentio, another boon for the Asus is that it won't make as large of an impact on your wallet over time. Even still, you shouldn't be surprised to learn that neither HP comes close to earning an Energy Star certification.
HP includes a standard one-year warranty with the Pavilion p6510y, with just enough free support to keep you happy. Within the allotted time, you get 24-7 toll-free phone assistance, a comprehensive list of Web help, including manuals, FAQs, live customer service chat, and driver updates.
