I'll answer first so you get an idea.
I play around with Funtoo on this desktop. I'm dual-booting until I become comfortable enough with it. Hopefully I'll become a Linux whiz sometime in the future. I also play around with programming, just python for now.
The build is pretty simple:
Mobo: MSI MS-7788
CPU: Intel Pentium G630
RAM: 4.00GB
GPU: NVIDIA GTX650
In the future I hope to build a new more powerful desktop for faster compile times and such.This one is okay for now because I'm really just a beginner.
I think it would be cool to have a list of working hardware builds with different use cases, listing how long it takes to do things like compile a kernel or commands like:
emerge -auDN @world
. :D
