It seems you were correct about laptops being more expensive in Sweden. As far as I could surmise it appears it will be cheaper to order a laptop from the USA and pay for international shipping. I seems that Sweden doesn't charge any import fees or VAT as far as I can tell. You also ask:
What would save a 'considerable' amount - buying from the provider with above features preconfigured or simply buy the hardware without OS(bare metal) and then install RHEL by myself?
There's a third option, buy hardware that already comes with an OS (most system do) and then install RHEL yourself. The procedure is identical even if it came without an OS.
Comes right out of the box with 32 gb of RAM. Unfortunately, this laptop is not capable of an upgrade up to 64 gb of RAM, despite the i7-7700 HQ being capable supporting 64 GB of ram over 2 slots. Also if you're wondering about the powerful discrete graphics card, laptop manufacturers catering to this level of RAM capacity usually end up being gaming capable laptop purveyors where this is standard. This just so happened to be the cheapest laptop I could find. Perhaps if you use your Red Hat linux system for video rendering this may be more useful. MSI doesn't sell laptops directly.

This option explicitly supports 64 GB of RAM. Most mobile systems don't really support 64 GB RAM upgrades because there isn't really a market for gratuitously expansive memory in laptops, as most people would purchase a non-mobile desktop/server system for the average user case scenario (hosting, servers, etc.). If you are thinking about 64 GB of RAM in the future, I would advise explicitly buying a 64 GB supported laptop out of the box as it is likely most laptops will only have 2 slots for memory meaning an upgrade will be a full replacement, as you won't be able to add to your existing memory infrastructure. Effectively, you will need to buy 2 32 GB memory sticks which will cost you in the ballpark of 1793.59 - 3587.18 kr. If you try and skimp on RAM costs, it is also likely you will buy poor latency (Higher CAS latency values) RAM, which will have inferior timings and therefore more delay. If you want to purchase a configurable system from the manufacturer here's a link.

Edit: Dell precision series response (link was too long to fit in a comment). This is the cheapest (purchasing directly from manufacturer) precision series laptop configuration that supports 64 GB of RAM. It will cost you 38,076.75 Kr, and isn't a very good deal.
