More and more PC vendors rush into ION-based platform market. Previously we have Asrock, Acer and Asus, and now iChill N330 ION. It all depends on what you want, Aser's AspireRevo is cute but it does not have a DVD/BD drive, it comes with a 4-in-1 card reader instead. ASRock Ion is nice too but it lacks of an eSATA for your external hard disks. And mind you, most of these ion-based bared-bone platforms do not have the complete components inside, for example, RAMs and Hard Disk may not be included in the package.
On another hand some vendors would just release plain boards for the consumer market, e.g. ASUS
AT3N7A-I and INNO 3D iChill N330 ION, both provide eSATA for faster excess to your external hard disk storage.
