And to others, I see that people have told me not to buy Dell, Compaq, Acer and HP too, which all are really great brands. So perhaps I should not go with what people say, cause everyone has different opinions. I still think to go with Acer, this one is not that costly and looks good. And anyways, these all are just brand who join the part to make a good computer. They don't manufacture the important elements like processor or RAM. It's all about their services (which I don't need for software), and their outer body reliability.
And towcows, I'm kinda good at computers too. Doing programming since I was 11-12 years. And I'm also doing engineering in computers. So I know a little too. But I'm actually much into softwares, and I hate hardwares, lol...But I'll give you the link to the model which is in my mind at the moment...
This is the one, Acer Aspire 5740:

I'm planning to go for Intel Core i5, and Linux pre-installed in it (This page doesn't shows that, but I read it at many other sites). And about HDD, I actually want that minimum. Cause I think using external harddisks is better, in case of laptop damage or anything that makes it not to work. Then I'll atleast my data will be safe and I'll be able to access it on my desktop computer, but I see that all the laptop above 2GB RAM atleast have minimum 320GB HDD, so with this one, I'll either go for 320GB or 500GB perhaps. I still don't know the price of this model with the configurations I just mentioned. I'm gonna find it out today. There is this list there, 5144, 5255, 5309, 5513, 5749, 5780, 6025, 6378, 6395, 6491, 6979, which probably are the various models of 5740 with different-different combinations of RAM, processor, and HDD.
Apart from this. some people have even told me that there is not much significant difference between 3GB ram and 4GB ram, and Core 2 Duo will also work great. So keeping this in mind, the Acer Aspire 4736z is good:

This one is really very cheap too. But I'm not sure if this will last for years or not. Cause already softwares' minimum requirements have reached 2GB RAM, I could hit minimum 3GB anytime. That's why I'm thinking to go for 4GB RAM. But it's true that there is not much significant difference in them, then I'd go for 3GB. Really confused with this RAM + Processor selection.
PS: And I want the model to be complete black. Whichever I choose, should be black.
