I'm happy ... I evaluate a noise like a classic because the noise is that what you set ...
well ventilated case ... nožnost put a lot of fans ... but beware it to make sense, and so there was no wind against each other ... looks decent oh those sheets ... a few years ago were crates of sheet metal, the lame today ... I feed mine and who has power to board 8pin up on the board so tight he reaches :-) absolutely do not understand why on one side at 5palc. Mechanic aka dvd-rom mount screws on the other side ... screwless mounting length of the cable from the front panel ... some tight (of course depends on the board)

I must admit, I fixed the compromise, when I bought it, I bought tú Nejlevnější with USB 3.0 and dust filters. No lenže when it was written in dust filters, so I expected filter on each hole for the fan and they are only two - on the front panel and the hole for a source, moreover, are not metal grids instead of conventional fabric filters, thus, smaller particles of dust probably will not be good filterable . But anyway, the price was good. Also part about it is the location of the mine resource and organization cabling. Likewise a hill holes for the fan, but in my case, what I wanted to housing - a tunnel without undue holes, as it is with us awfully dusty, I had to clog hill holes. A further negative aspect - is fairly low, though in most Narva better heatsink on the processor, so it will not give into it from the top of the fan.
Option to fit many Vetráková Basic organization cabling USB 3.0 A basic anti-dust filter and Odhlučenie 3 * / 5, can be heard at night but during the day by the open window, you will not even notice it Bezskrutková installation HDD / DVD Many holes - the need to clog up when you want to run into it from dust and have no Fans projecting outwardly 9x3,5 "+ 2x5,2" no positions only 2x2.5 "bezskrutkové handles, moreover, only one side (although according to me it is for 5,2 "enough) and 3x3,8" bezskrutkové handles!

Quality Mark XY possibility to use ventilators to cool
ATX plate sufficiently to readily and quite a large amount for utilizing the maximum quantity fan Nothing I not found

totally silent running all fans fast clamping discs possibility of mounting a large amount of disk spacious well it handled on removing the front panel for mounting the CD / DVD drive is to be a bit of brute force (the whole front part must break away from the rest of the cabinet and snap it again after installation)

Well, quite nice and airy classic size (midi tower) - seats up to this was all possible. Practically solved insertion HDD and DVD-drives. Well-placed Power button, reset and placement of USB ports To my taste too big (was not for me) view of the many vents should nezaškodili filters from dust. Built-in fans are too loud.

Very suitable housing for demanding home users who need a decent breeze with minimal noise for a good price.
Very low noise, large wardrobe to the composition of standard hardware. Decent draft in the cabinet with mounting a large number of fans 120 mm. Missing position for fixing SSD disklů and mechanic screw less installation on only one side, the back side of the cabinet is necessary to use screws (for mechanics, with disks operate from both sides klipzip).
