Bro I want something that's jacked
Like something with 16 gigs of RAM and 64 gigs of storage
for ₹10,000 ($120) ? 
what he said ...
keep dreaming, or buy some old PC.
To make your dreams come true, wake up.
Life has taught me that if life gives you lemons, make sure you know whose eyes you want to squeeze them in.
I found one with 256mb flash and 512mb ram
still no 16GB RAM and 64GB disk ...
it's a good device though, just keep in mind the available flash space is nowhere near 256mb.
The most jacked one I could find was the Turris Omnia but it's not available in my country
Netgear WAX206 has no USB.
Yes, that's a...problem
Someone help it's a rather tedious task to search through the list of supported routers.
Why didn't I think of that?
Thank you.
I couldn't find it
couldn't find what it ?
what about the Banana PI R3 ?
Still not able to decide?? 
Work in progress, it takes time for a device is supported.
After @mj82 submits his work and it gets approved by the OpenWRT project, its officially supported.
But I sense you are in a hurry, so go with an already supported device however as the comments in thread suggests it will not be a fast and easy process.
Afaict you could either lower your expectations, pay more money or go the experimental route with @mj82's work.
