Had a good experience with Qubes for years. Unfortunately due to reasons I may not specify I am no longer able to use Qubes. I promise however that I will return with a better hardware 
My hardware has been low range even at the time of purchase, and I would say my experience has been “usable”. Definetly recommended for better CPU/MB and more RAM.

Qubes overall was nonbuggy and could run for a very long time stable without a machine shutdown. However, I noticed an audio issue when turning the machine on for a long time (weeks or months). I’m not sure if this issue is known in the community, but I will write down some details:
At fresh boot on, audio is clean. (By the way, I don’t use audio qubes.) However while Qubes usage accumulates (either by time or the number of qubes I turn on/off), gradually all audio is slowed down and eventually becomes unhearable. Note the word “gradually”. For instance for the first one or two few weeks audio is fine. But then the audio becomes a bit laggy: x0.8 speed. Later like a month passed it is playbacked like x0.25 speed, bearly audible.
Interesting though, is that when I mute a video by a button on the video or on browser tab, or on media player, suddenly the video playback becomes normal speed. So clearly it is an audio glitch not a video one. I suspect it may be a memory leak…? Inferring from the fact that this laggy audio becomes apparent gradually as time passes since machine boot. But I can’t confirm since I’m not an expert, and I cannot help debugging since I briefly have to install another OS.
The bug is temporarily resolvable on machine shutdown or wake up on memory suspension.
One more downfall of Qubes I think is the inability to suspend to disk. But I understand this is a limitation of Xen and is not resolvable from Qubes.
Other than those, Qubes served great computing experience. Thanks for the development/maintenance and kindness from the Qubes community.
