Giada’s Slim-N20 is available for $449 on Amazon.com. It comes with 2 GB of RAM, a 320 GB hard disk, and the Windows 7 Home Premium operating system. Our white plastic test unit has an elegant Apple-ish look to it, with a brushed metal accent around its edge. It’s hard to believe how far we’ve come. According to PassMark, the Atom D510 inside the Giada N20 is roughly equivalent to a 3.73 GHz Pentium 4. While this is the only 1.66 GHz Atom D510 CPU in our test group—the other models use the slightly faster 1.8 GHz D525 model—Nvidia’s Ion 2 graphics chipset runs at the same 533 MHz core/1230 MHz shader/790 MHz RAM speed across all three of these PC

The Giada N20 is one of the slimmest PC’s: The white painted square chassis is about 7-inches, and about 1-inch thick. When mounted on the included stand, the N20 is about 8.25-inches tall. You could hide it behind an HDTV easily–it’s a PC that won’t be seen or heard. There’s a little bit of fan noise if you have your ear next to the system, but it’s more likely that any cable company DVRs you have in your living room will be louder.

With its dual-core Intel Atom D510 processor and 2GB of DDR2 memory, the N20 didn’t break any speed records on our benchmark tests, but that’s to be expected. Like the Lenovo IdeaCentre Q150 ($399 direct, 4 stars), the N20 took over 12 minutes to complete the Handbrake video encode tests (12:19) and over 23 minutes to finish the Photoshop CS5 test (23:39). Both systems are within a dozen seconds of each other on the multimedia tests, so it is a good bet that 2GB of memory and an Atom D510 processor are better at displaying multimedia than working on it. If you need to actually edit your multimedia on more than one occasion a year, you’ll be better off with a more capable machine like the Asus Essentio CM1630-05 ($479.99 list, 4 stars) or Apple Mac mini ($699 list, 4.5 stars). The N20′s ION graphics are more HD oriented than 3D, but at least it will run 3DMark Vantage at the entry setting (3,371 points). You could theoretically play light 3D games on your HDTV on the N20, but I’d bet you’d rather use a Sony Playstation 3 or Xbox 360 around if you were into gaming.

The hallowed Think branding finally spread out to the land of AIOs earlier this year and we just had to wrap our paws around some of that signature matte black plastic to see what’s what. The ThinkCentre A70z represents Lenovo’s most direct assault on the eco-conscious office manager’s checkbook, coming as it does with minimal packaging, built out of recycled and recyclable materials, and significant energy savings relative to orthodox desktops.

In our time with it, we found the A70z to be a well built and capable little rig, but the question you most probably want answered is whether the premium branding we associate with the tank-like ThinkPads can be trusted to deliver a similar superiority in hardware and construction in the all-in-one arena. Click past the break for the answer.

When IBM gave up on making regular computers back in 2005, some computer purists worried that the magic of the ThinkCentre and ThinkPad brands was gone and that the legendary solidity and build quality would also disappear.

The ThinkCentre A70z looks like a simple all-in-one PC, it’s a desktop system with PC internals built into the screen, rather than sitting in a separate box. It has the standard Lenovo ThinkCentre color scheme, gray/black high-quality plastics with a matte finish. There’s a speaker bar located below the screen and a Webcam above the screen. There’s a notebook-style DVD burner on the left side, 3 USB ports, and headphone/microphone jacks on the right. The back of the unit is clean and organized, below the kickstand there are three more USB ports, the Ethernet port, and a serial port. While serial ports are rare on consumer desktops, they still may be needed on business desktops for older peripherals like magnetic card readers and bar code scanners.

Asus EeeTop PC ET1610PT comes with Intel Atom processor is supported by the D410 1.66GHz, 2GB RAM, integrated GMA 3150 graphics and 250GB hard drive. Asus  EeeTop PC ET1610PT screen has 1366 × 768 15.6-inch LCD and supports 802.11b/g/n WiFi.

Asus has just added a new nettop to its online selection in the form of the EeeTop ET1610PT. The letter ‘T’ at the end of its name signifies that it will sport a touchscreen display, and you can expect a standard screen version of this nettop to become available without the letter ‘T’ at the end. Its list of features include a 15.6-inch 1600×900 resolution screen, integrated Intel GMA X3150 graphics and the Intel Atom D410 processor. 802.11 b/g/n Wi-Fi comes built-in, as are six USB ports, a 5-in-1 card reader, 0.3-megapixel webcam and an Ethernet port.

Asus is apparently preparing to launch its first all-in-one PC with Intel Atom Pine Trail processors. The company has been putting out desktop computer-in-a-display systems under the Eee Top brand for a year or two. But the Eee Top ET1610PT will be the first to come with a single core Intel Atom D410 Pine Trail processor and integrated GMA 3150 graphics.

The PC will feature a 15.6 inch, 1600 x 900 pixel touchscreen display, 802.11b/g/n WiFi, and Windows XP. That’s right, Windows XP, not Windows 7. At least that’s how the computer is expected to ship in Italy, where Netbook Italia reports it will sell for 400 Euros.
