as for sound cards, im not very knowledgeable about it so ill leave it for the other sifus to help
but some say Creative is a good brand for sound cards

well, on a stock cooler, the temperatures should be normal unless you have really bad cable management. if you want extra cooling, check out CM Hyper TX3 Evo at RM79 or CM Hyper 212 Evo at RM120+

both are solid performers

as for recommendation above, i checked from Viewnet Lowyat Plaza price list. but stock is subject to availability

yep, just bring to them and theyll get the parts for you. furthermore, buying all parts from them will allow you to get bundle discounts

yeah, they will do that for u..no charges
