CPU
AMD Ryzen 5 1600- Rs 16,900
Motherboard
MSI MOTHERBOARD A320M GRENADE - Rs. 6250
( I don't think you will get the Gaming Plus for that rate at amazon)
RAM
G.Skill Ripjaws V Series 8 GB (8GBx1) DDR4 2400Mhz (F4-2400C15S-8GVR) - Rs, 5,700
(Take 8 GB single RAM kit for now.Upgrade to another 8 G stick later on if needed)
Hard Drive
WD HARD DISK 1TB SATA BLUE WD10EZEX -Rs, 3,400
PSU
Seasonic S12G 520W – Rs. 6,700
(Do not crimp out on this as this thing will last for a long time. I bought a Corsair VX550 which was made by Seasonic in 2010 and its still running in my gaming rig to this date)
Monitor
LG 20MP48HB IPS Panel- Rs. 6,700

Case
The DeepCool Tesseract seems good for the price. But in case you cannot find it go for Cooler Master K380 – Rs. 3,500
Total
Rs. 49,150
IMHO the Ryzen 1600 is overkill keeping in mind your budget and usage as you will have to crimp on the RAM and mobo to fit this budget
