Fastest way to farm components right now?

I'm after high-power components for crafting — the usual suspects: CPU, GPU, Motherboard, Memory, Power Supply. Component power rolls 1-10, and higher-level crates (treasure crates especially) roll noticeably better, so opening twenty low-level crates starts to feel like a waste of time once you're past the early game. So: what's your route? Do you sweep a particular area for crates, or skip the grind entirely and buy power 7+ pieces off the marketplace while someone else does the farming? Post your GP-per-hour estimates if you have them.
