I've sort of been interested in getting a new desktop PC (though I don't think it's time yet).
My needs are as follows:
* Target game: Bard's Tale 4. This is the game I want to be able to play, and it isn't likely that I'll want games more demanding than that.
* Will be using Linux, and do not want to use proprietary graphics cards.
* I want to avoid NVIDIA cards, as that company does not provide open source drivers for their graphics cards. (Treat them as having negative value; a PC with an NVIDIA GPU is less valuable to me than an otherwise comparable PC with only integrated graphics.)
* Should not have worse specs than what I have now (16GB RAM, i5 4670 CPU).
* Would like the computer to be capable of VGA passthrough (assigning a GPU to a virtual machine, allowing gaming in the VM).
* Would also like it to run quietly, especially while idle.
Also, I remember years ago when I could easily customize prebuilt computers from the major brands (like Dell and HP); what happened to that?
Then find a store to assemble your PC for you.
How much does this typically cost?
