$400 Aluminum Heads Or Not?

Nice score.

I used to have a friend who built his own extremely high end computers, and built a new one every year.
They averaged about $3500 in parts.

About every two years, he'd sell me one...for $500.

Even at 1-2 yeras old, they were still about twice the performance of the top of the line major brands.
They also came with "tough love" tech support- all specs and docs but no coddling.

That's one of the things that got me into the IT industry.
