Linux Laptop under 40k

I am looking for a laptop which will be used to run only Linux (specifically openSUSE). I am currently looking at the following specs:

1.) i5 Third Gen processor
2.) 8 GB Ram
3.) Integrated Graphics
4.) Preferably one without heating issues
5.) FreeDOS as the base OS
6.) Wireless Drivers compatible which work out of the box in Linux

I will be using the laptop primarily for development applications on Linux.
My budget is under 40k. Please suggest a suitable laptop for this config.

Thanks in Advance
