No it is not. The best you can do is customize your laptop(as in the case of Dell). But buying individual components and then assembling it is not an option
Its not possible in India. In US some companies do that. But even then we can get a chassis and do the assembling ourselves since sourcing the mobo is difficult AFAIK. Also assembling is tricky.
Some time back i saw custom made laptops for gaming. You cant really assemble them but you can choose from the whole config-amount/type of ram, hdd,mobo with supportive gfx card, dvdrd, multi cardreader, even casing fan & cooler, casing color/make/material, keyboard-simple/fancy/tranparent led and even a fancy trackball etc. I guess that was some korean site which i had to translate to english via google translate.
