This is what you should look at

But here are your options on that range

And as for your 19" monitor req., If I'm not wrong 19" monitor's are not get manufactured nowadays. It's 18.5" (Correct me if I'm wrong)
Well......I suggest to go for assembled one's. You'll get much better rig than branded ones in the same budget.
Well......Here I suggest an assembled rig :
AMD Athlon II X2 240 @ 2.8k
Biostar TA785GE @ 3.7k
2GB 1333MHz Transcend DDR3 RAM @ 2.5k
500 GB WD Blue @ 2.3k
Sapphire 512MB DDR5 HD5670 @ 5.2k (If you want gaming too)
Benq G2020HD @ 6.3k (20" Widescreen)
Zebronics Bijili @ 1.1k
FSP SAGAII 350W @ 1.4k
Logitech/Microsoft Keyboard + Mouse Combo @ Rs. 700/-
L.G. SATA DVD-Writer @ 1.1k
Altec Lansing 2.1 BXR1121 @ 1.1k
Total 28k (Approx)
If you don't need a discrete graphics card(785 Chipsets have inbuild ATI 4200 Gfx card), you can opt for better mobo and better proccy
Like AMD Athlon II X4 620 and Gigabyte 785 U2SH/UD2H
Well.......wait for other members to come in and reply.
