Hey, i know this is not the place for trading but I actually just dismantled one of my rigs - removed the GPUs and PSUs so I have the frame with all other components left. Here's the config:

Open Aluminum Frame
Mobo: Asus Z270-P
Processor: Celeron 3900
RAM: 4GB DDR
64GB SSD - with Windows 10 installed, all settings adjusted for mining and drivers installed
8 Risers installed
Also has a connector for 2 PSUs installed

The system was built end of Jan. I don't have any use for this config so I'm fine selling for around 80% of retail cost, say $280 ? Let me know if interested and I'll take pictures when I get home and send them over.
