I'm not opposed, exactly. Bang for the buck the Antec is better. The Corsair is a CWT made unit, and the actual max 12V is LESS than the Seasonic. It's a fine choice normally for a very low budget, but I find the Seasonic very compelling at that price.
I'm surprised it's still available, but the Neo Ecos were never released to reviewers... Makalu did a review though that was quite good. This is a professional grade review:http://forums.guru3d.com/showthread.php?t=317192
