Acer Revo 3600
Acer’s overhauled Aspire Revo 3600 nettop picks up where its predecessor left off. Like the original Aspire Revo, the new 3600 model supports HD video courtesy of Nvidia’s Ion platform, but the latest iteration trades in the comparatively anemic single-core 1.6GHz Atom 230 processor for a 1.6GHz dual-core Atom 330.
Right off the bat, doubling up on cores will come as a boon to anyone, um, aspiring to do more than basic tasks with the Aspire Revo. Other specs include 4GB of DDR2-533 memory, an HDMI port, and VESA mount compatibility.
Haleron H-BOX (459$)

Lenovo Q110/Q110
The slow wave of NVIDIA Ion-based machines continues to wash in — as expected, the Lenovo Q110 nettop is now on sale. We’d actually wait another couple weeks to score this rig with Windows 7 preloaded, but if you’re into Vista you can grab it right now for $399 with 2GB of RAM and a 160GB drive and take a free upgrade disc when it’s available.

Processor: Intel Atom 230 single core, sis672 chipset
Memory: 1 GB DDR2 on Q100, 2 GB on Q110

LG XPION
Apparently not content to let ASUS have all the fun, LG’s just announced the XPION X30, its first Ion-based nettop. This little fella features an Atom N230 CPU, 2GB of RAM, 250GB HDD, and ships with Windows Vista (for the time being, at least). Aside from sporting six (count ‘em!) USB ports, it weighs in at a mere 2.4 lbs, draws just 40 watts of power, and can be VESA mounted to the back of your LCD. But never mind all that — as long is it allows us to stream American Ninja from Netflix with minimal fuss we’re happy. Debuts tomorrow in Korea.
Pegatron IPP7A-CP
No specs available yet… but probably it will have a single Atom, 2 gb ram, 160 Hd… and so on!
Este não é um ION… é uma plataforma muito mais potente mas mais cara! (699€)
Fujitsu ESPRIMO Q1500
Rather than using an Atom processor or similar, the Fujitsu Esprimo Q1500 makes use of a 2.8GHz Core 2 Duo T9600 processor, along with 4GB of RAM, a 320GB hard drive, and a nice selection of six USB 2.0 ports.
Fujitsu Esprimo Q1500
The reason the Fujitsu Esprimo Q1500 is of great interest to this site is it's powerful specifications, along with an optional slot-loading Blu-Ray drive and HDMI output. This makes the Fujitsu Q1500 a great choice for use as a HTPC / media center, as it's more than powerful enough to decode and playback 1080p HD to your HDtv.
The machine is also energy efficient, using only 19 watts of power in idle mode.
Sintam-se livres de acrescentarem mais alguns! 
porque no site diz que tem duas entradas e uma saida que na minha vista de ignorante parece que dá para ligar (e sim é para ligar em HDMI).
