The HP Pavilion a6400z desktop is a versatile machine aimed at meeting your basic home, school, or work computing needs. Our review configuration of the a6400z came in at $340, but with a few key upgrades on HP's Web site you can turn this into a much better system for less than $100 more. If you make those upgrades, you'll find yourself with one of the best budget systems around. In its current configuration, the a6400z compares well with other systems in its price range, it's just hard to get too excited about it, knowing what you can get if you spend just a little bit more.
The a6400z has a simple, elegant chassis design that looks a lot like the HP Pavilion Elite m9040n with a similar glossy and matte-black palette. Unlike that system, the a6400z's lower half is practically empty except for the HP logo and a few stickers--no dubiously useful removable hard drive bays. The a6400z's lines are symmetrical, clean, and unassuming--exactly what you'd want in a no-nonsense budget system. The lowest bay features two USB 2.0 ports, but that's it for the media bay. Our review config came with no media card reader, but HP offers one for only an extra $10. That's just one of the upgrades we suggest.

The eMachines T5254 compared above is eMachines' most recent $400 desktop. We have reviews of last quarter's $349 T3642 and the $429 T5246, but with the model outlined above, eMachines appears to be splitting the difference with the new T5254. Compared with the $340 HP, it's no surprise that the $400 eMachines looks like a more robust system. The eMachines' key differentiators are the faster, higher-end Athlon BE-2350 chip, the larger hard drive, and Vista Home Premium. If you're willing to spend $420, you can bring the HP up to a par with those features, and also include a faster, more robust 2.3GHz AMD Athlon 64 X2 4400+ chip.
As configured, our Pavilion a6400z review unit was not much of a performer, especially when you compare it with eMachines' T5246 from last quarter. Still, we can use that system to project how an upgraded a6400z might fare.

As you can see, the Pavilion a400z clung to the bottom of all four speed tests. It only edged out the single core eMachines T3642 on tests where having multiple cores has an impact, such as Photoshop. You'll notice that the eMachines T5246 beats the HP on every test, though, and by a significant margin. The reason is because that eMachines model has a 1.8GHz AMD Athlon 64 X2 4000+ chip in it. Now imagine if the HP were configured to match but included the even faster 2.3GHz Athlon 64 X2 4400+. Without actually testing it, we can only speculate how an upgraded version of the a6400z might perform, but all indications are that it would deliver the best bang for the buck in this price category.
The a6400z being a decidedly budget system, it really is a basic PC. HP offers options for more RAM, a larger hard drive, and wireless networking, but video-oriented hardware such as graphics cards, TV tuners, or Blu-ray drives is absent from HP's configurator. You get some room available for aftermarket upgrades, including a PCI-Express graphics card slot and room for a second hard drive. The system only has two memory slots, however, and both are currently occupied, so you'll need to discard the current RAM if you want to expand it yourself.
Software-wise, the Pavilion a6400z is equally spare. The Windows Vista Home Basic experience is not significantly different than Vista Home Premium. You lose the translucent windows and the other special visual effects, but most of the core functionality is there. The one feature you might miss is Windows Media Center, but as this is a traditional desktop design, we don't suspect you'd use this system as a living room PC. We're also not surprised to see that HP retains its hold on the Most Cluttered Desktop award. (Really, you need a desktop shortcut to eBay?) At least Total Care Advisor, HP's software suite that provides system care advice, remains useful.
HP offers a one-year parts-and-labor warranty with the purchase of the HP Pavilion a6400z. You also get 24-7 toll-free phone support, as well as a service that allows an HP technician to control and fix your computer remotely. You can also extend the warranty in two-, three-, and four-year increments, and HP also offers plenty of support resources online.

No Available SATA slots and only two memory slots..
Pros: The price is right on this HP computer and it has on motherboard gigabit ethernet.
Cons: I was shocked to discover that the a6400z has NO available SATA slots on the motherboard. There are only two total on the board, and they are used up by the operating system hard drive and the DVD drive.
