i think you shall not installing steamos
windows or linux
SteamOS is Linux, it's based on the Arch Linux distribution
You could try SteamOS, they will even have way better desktop support from now (as until now Steam mostly targeted handhelds instead of desktops)
i want to play runescape on runelite and newer games with midrange graphics and will need a monitor (i do not play online first person shooter so very low latency is not needed)
something discreet, small atx motherboard, simple, quiet, no rgb..
and i would also recommend building your own custom machine rather than waiting for the steam cube to drop
(tho the cube would prob be around the $500-$750 price range and would fit your needs of something compact and small as a desktop, if not needing to run resources intensive tasks)
and maybe after getting comfortable with the SteamOS ecosystem, would suggest to just try out Arch Linux and with your new knowledges regarding Linux, to make it fit your needs with the same or similar tools that you would have used on SteamOS
id like to put max 2000$ canadian dollars for the computer and 1000 max for the monitor..
i would personally go for the 128GB RAM version of the frame.work desktop
(CAD $2,859):
https://frame.work/ca/en/products/desktop-diy-amd-aimax300/configuration/newas it would be an upgrade in my case, since AM4 socket doesnt go higher than 64GB RAM
most gamers dont have the need for a GPU but those integrated graphics on CPUs are very powerful nowadays on those newer chips
and even on AM4 socket without a GPU am still able to play +10x instances of D2R without too much hassle
as documented a bit over there:
https://forums.d2jsp.org/topic.php?t=106605329&f=148however, for your case
wouldnt necessarily recommend the framework desktop (nor the 64GB RAM version of it (non-upgradable))
as for your needs, you could build something for cheaper that would still do the job
laptops are fine since they can still have similar chips without needing a GPU
but desktops do have proper cooling for more regular use (and laptops break more easily, less modular, more annoying with dust maintenance)
you could max out an AM4 build with like 5700G chip (or similar with integrated graphics) and 64GB RAM (that is also used as VRAM) for way less than CAD $2000
or you could do similar on AM5 socket, with the possibility to upgrade to 128GB RAM later on (as it would be modular), just by adding RAM sticks later than having to completely replace them
could i split my current ssd in 2 partition (i use windows 10) and install and run one of those os on the other partition to see if it works well?
you could (it's called dualbooting)
but from experience it's way less of a headache to just have a separate ssd for that
either from having both plugged in and doing the dualboot
or swapping one for the other when wanting to boot one or another
been doing the no-case and even on the M.2 nvme, no screws so swapping takes as long as a very quick reboot anyways
also that way dont have to have the headache to troubleshoot a broken GRUB after a windows update... (GRUB is the first thing that boots for Linux and is what's used to manage dualbooting)
