With a budget like that even my hands are begining to scratch in anticipation
Anyways Methinks some of the prices are a bit steep like AMD A64 3500+ S939 which is priced at 14,250 at your place whereas my friend out here recently got a AMD A64 3800+ S939 (Venice core) for 12k.
Nextly Dump the Hynix Ram idea as the one you are stating is way too pricy and that too for that cheap Hynix brand which roughly costs around 5.5k for a single 1GB module.Better go in for Transcend 512*2 PC3200 (400Mhz) modules and activate them in Dual channel mode to see things Blaze past by & each sticks will be costing atleast 2.5k each.
As for the Monitor i suggest a Acer AF715 costing 6.5k which is posibly the only monitor i know currently that supports the Max resolutions as high as 1600x1200 @75Hz.This will be quite enough for you but still if you want to go for a 19" do consider a Viewsonic E90 series.
Graphics card for such a config ain't a 6600GT but either a 7800GTX or 6800GT atleast as both these cards can give amazing frame rates and the former is the Single most powerful card out there(Also the one to be drilling a hole in your pocket

).The sole reason i am asking you to ditch the 6600GT is because the upcoming games in order to be played at uber high resolutions needs a High end card and 6600Gt wont last that long enough to support them @1600x1200 resolutions with AA and AF.So only if the budget allows you then you can opt for this or atleast settle for the Powercolor Radeon X800XL 256MB PCi-E version for 19k.
Optical Drive IMO would be the Lite-On SOHW-1673S DVD Writer which must be around 4.3k.How can one think of a Config without a DVD Burner
I would say the Antec Super Lanboy is a good bet for the any gamer's Cabby Choice.Complete with LED set up this Cab is every gamer's Eye candy.The last i know it costed somewhat around 5.5k.

The rest of the Specs are quite in place and if you consider the THX version of Logitech's X5500 it will blow the entire budget out of proportions not to mention exceeding way above the 1 Lakh mark.So my final question remains what is your Final Budget? :roll:
