How to buy Lenovo ThinkCentre M72e Tower Desktop?

I'm from Kolkata, India, have visited many exclusive stores of Lenovo, none of them having this product available. I want to buy this product with the following configuration:

Intel Core i5-3570 Processor (6M Cache, 3.40GHz)
NVIDIA Geforce GT620 DP
1TB 7200rpm SATA HDD
ThinkVision LS2223 21.5-inch FHD LED Backlit LCD Monitor… With all other settings.

Please tell me how to get this desktop.

Well that model is meant for businesses, so it is unlikely you can purchase it at all.

Well… You can simply go to www.flipkart.com and get your desktop booked. You can trust this site. Really it is a very good online hub for all kinds of products… Moreover you can give cash on delivery. This online store is rated highly.so you can really trust this and order your desktop now immediately. The next best opt is to go to www.jabong.com. For the above features you hav said, these two sites are really gud dude… So have a look.
