More Details:

The internal chassis continues the silent performance traditions and carry over the same removable drive bays and features as the P180/182 enclosures. You still get the rubber grommets, screw mounts, and tooless clips to set up your ROM and hard drives accordingly. If you feel so inclined, you still get the extra fan mounting wire clips to add another 120mm fan. But, with so many already existing case fans, another would just be practice.

Removable Bays

Got Management?

I've personally compared both the removable drive bay clips and Antec's rubber grommet and screw methods to see which was louder and the Antec method is much quieter. Very few ROM drives kick up enough vibrations anymore unless it has an internal issue or is some back-corner of the world name brand that hasn't caught up to the rest of the industry. If you are out of room and need to use the clips, they will do just fine for quick removal and rarely carry over large vibrations due to the sound dampening and better chassis. The noise level just can't be silenced in many ROM drives. The better the name, the more chance of success getting one that is much quieter than cheaper brands. Hard drives, on the other hand, are getting much quieter now. Some older drives still make those odd noises as the head moves around. Antec's hard drive mounting method cuts down on vibrations dramatically over the clip method.

Another improvement is the removal of the black plastic chassis slides that were suppose to help control wire placement. The P190 uses two plates with 1 thumb screw holding each in place. The larger plate allows you to install or remove the power supplies and offers some extra space to run wires if left out. You could do the same with the P180/182 as well, but you still have to remove the inner PSU cage to maintenance it. Since, dual or larger wattage power supplies mean extra wires, this could help alleviate the cramped wires coming through that small hole. It would be nice to see an optional plate included with the P190 so you wouldn't have to leave it out.

Inside the bottom area, you can see the non-modular 650 watt PSU which powers up your motherboard and add-in cards if any. The 550 watt does have modular cable ports that are used with the included cable bundle in the P190 box which make a very snug, secure connection. The 550 watt PSU provides power for your graphics cards, drives, peripherals, and any other modifications you might add. This particular method of separating the power draw is pretty ideal for a serious BTX based system, or for the fanatical users that want to guarantee the ultimate success in their efforts to build one very powerful graphics or overclocking system.

1200 Watts Total Power

The NEO Power series isn't one of Antec's newest power supplies, but anything can be revamped or improved. Here you can see each specification and what kinds of power you can expect to receive from the duo. Both the Neo 650 and 550 offer three 12 volt rails each, making for a total of six. The 650W offers 19 amps per rail while the 550W offers 18 amps. The 3.3v and 5v rails offers 24 amps on both power supplies, while the 550W only offers 20 amps to the 5v rail. The 650W is completely hard wired and the 550W offers five modular cable connections. Between the two, you get more than enough cabling to satisfy anyone.

One other notable feature is the PCI Express Card Holder which Antec has seen fit to offer as a very simple solution to very large PCI Express cards and include the feature in the P190. It's nothing more than a mountable black plastic holder that screws on to the side of the middle drive bay that helps hold large PCI Express cards in place. Some of the newest PCI-E cards are reaching 12 inches in length which equates in to a very hefty graphics card pulling on that half inch PCI Express slot. So, this could prove to be a valuable feature especially if you intend to transport your system to the next big LAN Party.
