I will be using CubesOS for day-to-day Linux tasks such as programming, YouTube Browsing and Linux gaming with KVM running if some games dont run on Linux very well (like GTA5 Online) as well as for testing other software and not-fully-trusted windows-native softwares.
I have checked out the hardware compatibilities and what not for the hardware i will be running. And It said to function pretty well on an older version. the only problem being is sleep not actually going to sleep.
Buy those component from a retailer
with a good return policy. You’ll be
glad you did if SHTF when trying to get
the GPU to work correctly with passthrough
and/or gaming.
For starters, you can’t run KVM in Linux since Qubes uses the Xen Hypervisor. Additionally, while GPU passthrough is possible in certain hardware configurations, it is far from a beginner’s setup and prone to issues that will require troubleshooting to solve. Also, I’m not sure how well supported that Radeon RX 6600 card is: you may be better off with an older Nvidia card (GTX 1650 or similar). Another possible consideration is the number of USB subsystems included, if you plan on using a USB Qube together with USB keyboard and mouse.
On the gaming part, if you plan to multiboot, that may work but, again, multibooting with Qubes is not recommended for security reasons and it’s not a beginner’s configuration either.
As someone else said on this thread, either you get a very good return policy on that hardware or borrow it somehow and test it first.
