OK budget increased to 24 k now
Dell has a desktop for that price with a 22 inch monitor. Though you will surely not be able to play games that put load on the pc they will use cheap components with a 400w or less psu.
I'd suggest wait and make a budget of 30k and get these.
Core i3 4150 - 7.5k with intel hd graphics. This will allow for light gaming and maybe games some games like PES on low-mid settings.
Mobo- Asus B85M-G - 5.9k
Ram - Any good ram kit 2x2gb for dual channel should cost about 2.2k as ram prices are low.
PSU - Corsair CX500 Rs. 3.5k (A good psu is a must, don't go for the cheaper ones or the corsair VS series. You could get a CX600 for 4.2k which is ideal.
Any good cabinet that you can use to add a gfx card later if you want or fans for cooling. 2k for this. According to an old digit article nzxt gamma was for 2.5k.Which has good spacing for cards and you can put some good cooling in that.
Logitech MK200 Keyboard and mouse combo rs.900 or so.
1k for a dual layer dvd writer.
I'd suggest a good 1080p (21.5 inch) or at least a 900p (20 inch) monitor for watching movie as a secondary use. Will cost you upto 8k for a 21.5 inch monitor. Lesser for the 20 inch one.
FYI - you will need to upgrade the power supply in future to a good 600w one if you plan on adding a gfx card like the gtx 960 in the future, if not then this config will suffice. A cx600 can run cards like the 960.
You can find these components cheaper locally, or you can even strike luck on the upcoming flipkart or amazon sales, if you prefer buting like that.
But if you are going to spend then wait and do it well, a 30k PC will be better than any 24k compromise.
