Excerpt: ou will not find a more powerful air-cooled case on the market than Antec’s Twelve Hundred—not unless you strap a box fan to the side of your chassis. That’s what it would take to challenge the cooling prowess of this full-tower enclosure, which features one 20cm fan on top and five 12cm fans placed throughout the interior. These six blue LED fans are attached to individual switches that allow you to tweak the strength (and sound) of each fan to suit your needs.
Pros: More cooling than a wind tunnel, elegant design, USB and eSATA front-panel connectors.
Cons: A tight horizontal fit, drive installations take forever, no screwless mounting.
Conclusion: I'm not that fond of plastic when used in computer cases, but Antec was careful to only use it where it was needed. However, the top portion of the case is nearly all plastic and it does take away from that heavy duty Antec quality I've come to love. Then again you have to look at the plastic top as part of the case design as metal would be nearly impossible to use due to cost. As for the remainder of the case, I was thoroughly impressed.
