I built this custom for myself a couple months ago but have since upgraded.
All parts are inspected, tested and fully working.
It is running an I-5 11th gen intel processor
Nvidia RTX 3050, discrete GPU (yeston)
16GB DDR4 3200mhz
256 GB NVMe storage,
fresh Windows 11 Pro install
I'd be willing to upgrade the RAM or storage for a slight extra cost if you want.
I don't recommend upgrading the processor, The small form factor means it has to move a lot of heat and the I-5 is just about that limit. Not that you really need to because that I-5 11th gen will run any game I've thrown at it.
I've tested modded Minecraft with shaders and Red Dead redemption 2 both with very solid graphics at 60 to 100 hz at 1080p.
I'm also willing to pre-install any operating system you like
It is very small at 18x18 by 4 cm
