I can sell you some C1 waterblock.
You can't mine until upgrade but you will be ready.
I have 4x. Also have pump and rad.
Eh, no thanks. I have some projects with the blades (CP2102 to USB, been wanting to try that out for a long time) for fun as well after that so I'm good. I'd be willing to buy S3's shipped for under 50 as well so if anybody happens to have any I'd be willing to purchase one.
