Hmmm.. Malaysia only got DM014H and DM174H afaik...

And yeah... difference in number becoz difference in config... There's several reviews about this laptop if you could find them... The most comprehensive one to date is the one by laptopmedia.com... Also in notebookcheck.com (got a translated link)

Yup there is screen flickering issue as seen in laptopmedia review, but the screen used is Samsung but mine (M'sia model) has AUO screen..
Cooling I think is good based on some reviews... Don't judge cooling solely by looking at Prime and Furmark test because they are not reflecting day2day operation..

Keyboard I can say is awesome.. typing is very responsive and comfort even.. in long time... and the plastic used is high quality one... if use aluminium the you cannot get this price huhu..
