Areca doesn't make the high point rocket raid cards (which are medium
quality RAID cards).

Did you follow proper ESD precautions when building this machine??

Sounds like your hardware is bad.  Could be mobo / cpu / memory or
RAID card.  Does this machine "hang" every so often or anything?

I'd run memtest86+ on it first to confirm good cpu / memory / mobo.

Quick factoid from my days as an electronics instructor in the USAF,
95% of all ESD induced failures are latent in nature, either resulting
in catastrophic failure or thermal degradation some months or years
down the road.
