| Manual and Labeling |
+ Complete motherboard inscription and except the missing BIOS section detailed motherboard manual in different languages e.g. German, English, etc.. Easy devaluation of the manual, because the BIOS is explained only in the manual on the CDROM, where it doesn’t helps if one is in the BIOS! Furthermore the inscription is not good readable caused by the MicroATX format. |
