Will I be able to mine (lend) storage, cpu and gpu to iex platform and get rewarded for it?
Yes @andraxyz you will be able to do this. You may play the role of Server provider and get RLCs for that.
You can see this role joining the iex.ec market network after the release of V2 on the iex.ec roadmap.
