Wondering what I would need to get a 10sp cassette on what was originally an 8sp bike

Alright, I am new to the forums, and I just have a very extensive question that I need answered. What want to do is buy a BASIC rockhopper, and I want to outfit it with all good shifters, Derailleurs, brakes, new fork, etc. to make it as good on the trail as a bike 3 times the cost.
What I am trying to do is to get the stock 8x3 sp to a 10x2 (all the good gear that I can find is in 10x2). I am just wondering how I would need to modify the rear hub/ which rear hub I need to get.

I think I need this rear hub:
Robot Check

And this cassette (the 36h)
Shimano XT 10 Speed Cassette | Merlin Cycles

Please let me know if there are any other geometry changes/parts I need. Thanks!

edit: For the $700 mark, is the rockhopper a good choice for a hardtail 29er? Is there anything noticeably bad that I should replace?

If you're going to spend that much money already, why not step up to the Rockhopper Comp which will have a much better starting set of components. That would be a good ride to begin with, then you can ride the heck out of it then decide what needs to be upgraded.

You could easily convert it to a 2x10 drivetrain if you decided you want to. Wheels and Fork would probably give you the most noticeable improvement on the trail though, I've had 3x9 setups for years and honestly, gearing hasn't been my problem at all.

You could also find a new high-end 9 speed rear derailleur online as they are not as popular as 10s are now.

But either way I don't think going with a Rockhopper will be a bad choice.

Are you saying that the parts i listed are all I need to get it to be 2x10? I can't find 3x9 to be practical, and also, I am imbetween beginner and intermediate IMO at biking, so I don't think I would need the good components at the start, just as I get better.

The time and money you're going to spend upgrading a basic Rockhopper will bump you up to a "mid" line hardtail like a Crave.

To go 2x:

2x front derailleur, 2x front shifter, 10sp rear derailleur, 10sp rear shifter, 10sp cassette, 10sp compatible freehub body, and a 2x crankset.

With a Crave, you're getting a better frame and components...including the 2x.

Its only worth doing if you have an upgraded frame.

If not, its better to buy a new bike outfitted the way you want.

For the front everything you have already will work fine. You just adjust the stop screw on the front derailleur, forget that the shifter has a 3rd gear on it, and take off your big chain ring and bam 2x whatever. Both mine are 2x9 because I haven't felt the need for 10 speed yet, bang for the buck has been 9 speed. All you need is the stuff for the rear; shifter, cassette, and chain. Your current hub will be fine. Still after you put good brakes and forks you are still going to be stuck with a lowend crank, wheels, bars, seat post, stem, etc and it will cost you more than just buying a better bike with all the crap you want on it already. A good fork will cost you HUNDREDS by itself and same for the wheels.
