sorry, i skipped over the second half of the thread, but did anyone ask you what you were using the PC for?

I ask because this is pretty much the main idea that you'd build your rig around.
A gaming PC is different to a design+production workstation, which is different to a server, which is different to a crypto-currency miner, which is also different to the dual-purpose email reader/paperweight.

But you've made the purchase already, so i suppose it doesn't matter too much at this point anymore.
