Not sure if it's available in India but how about Samsung Galaxy Active 5

Unless you're rendering really high poly models it shouldn't be too bad, not sure about this thing's thermal performance though
That said whatever you end up getting, get a storage upgrade first
500Gb is not enough at all
If you don't mind me asking what exactly are you planning to do ...
I got mine from Meckeys

Neo Macro is pretty well known in the Indian Mechanical Keyboard Community, so I'd imagine they're pretty reliable, haven't gotten anything from them personally yet, but I do...
Yeah, they're definitely not as easily replaceable as some of the more popular mice
But on the bright side, in case the battery does go bad, it shouldn't be too difficult to replace, from what I know the battery uses a Standard JST connector
yeah that, I didn't replace the switches in the Orochi V2 because they went bad, but just like you I wanted something more reliable (and the GM 8.0 switches just feel better than the stock ones on my opinion)
Been using it for about an year or so and it's been great so far
