On the Inside
We begin our look inside by dropping the side panel. I generally don't pay a lot of attention to this portion of an enclosure, but there are two main features that need to be noted.
The first feature is a behemoth of a fan, affectionately called "Big Boy" by the folks at Antec. This monster is a massive 200mm TriCool fan and also includes a removable filter to boot. Since this is an intake fan, the filter is a good addition. The filter material is a light meshing that is easily cleaned with either air or a mild solution.
The other feature with regards to the side panel is something that I briefly mentioned earlier, the soundproofing material mounted to the inside of the panel. It is a plastic based material that is mounted directly to the side panel and also has small grommets to handle any light vibration that might be transferred. This helps keep noise from reaching your ears, and this is a good thing given the massive fans being used in the P190.
Going into the actual interior shows nothing out of the ordinary with regards to the optical drive bays. There are four, all of which are externally accessible, and all have round guides for use with the included rail system. The rails are the same as past models and while they do require the use of screws still, they are simple to install and work flawlessly.
Moving down the drive tower shows one of the two 3.5" bay trays. This top one is located in the primary component compartment and is designed for two 3.5" hard drives. This tray contains a pair of removable carriers complete with rubber mounting grommets to install your primary storage system and make sure that vibration is not an issue.
Directly below this tray is a single 3.5" drive bay that is externally accessible. This is for those who still make use of a floppy disk drive. Alternatively, there are several manufacturers now making media card readers that fit into a 3.5" bay, so this could be used for that as well.
Traveling to the bottom compartment shows us another 3.5" drive bay tray that will fit up to four more hard disk drives. While we do not see the removable tray system like shown above, Antec has made sure to include rubber grommets on all four insertion points to make sure that vibration isn't an issue. A simple thumb screw is removed to allow you to take the entire cage out of the system for easy hard drive installation.
Going back into the primary compartment shows the two top-mounted fans. They are powered by a standard Molex connection and offer adjustable fan speeds by means of the switches on the back of the enclosure. If you pay attention to the long tube just above the fans shown above, you'll note another unique feature of the P190...
That little tube is in reality an LED light that allows you to see what you're doing when you don't want to pull the entire box out from under your desk. It is mounted on a flexible rod and is powered by either a Molex (comes on with the system) or by means of plugging it into a spare USB header on the mainboard (light comes on as long as the motherboard is powered). This was a very nice convenience item and it can make things a lot easier when fiddling around under the hood while the system is still under the desk!
The rear fan is pretty basic and has adjustable fan speeds as noted earlier. From this angle you can also take note of the retention system for system for peripheral add-on cards. While not a tool-free design, the lip of the enclosure is small enough to keep from causing problems when installing graphics cards or other add-on components.
