Lian-Li's PC-X900 Enclosure Has Two Heating Zones, Tons Of Room

If it's not Thermaltake, it's Lian Li pushing the envelope in the PC chassis space. These two have been delivering cases that are weird, sexy or just plain huge, with the new PC-X900 fitting into the last one there. Built to support ATM/M-ATX motherboards, this absolutely giant enclosure is actually separated into two heat zones, and it also features four USB 3.0 ports, a single eSATA port, HD audio, three 120mm LED fans in front (plus two in the rear), seven PCI expansion slots, seven 3.5" hard drive spaces, three 5.25" optical drive spaces and a red (or black, or silver) coat that'll catch just about any eye.

The case is also designed to be tinkered with without having to use special tools, and 230 x 598 x 388mm (W.H.D.), you can bet you'll need a lot of square footage to fit this one into your home. It'll ship later this month for a whopping $439 - $499, in which case you'll be tempting to spring for just a bit more and grab the Level 10.

An Ultimate Mid-Tower/Gaming Chassis – Lian Li’s PC-X900
Tool-less & heat-zone designs maximizing effortless life and thermal solutions

4 May 2010, Keelung, Taiwan – Lian Li Industrial Co. Ltd. today announces its brand-new TYR series – the PC-X900 mid-tower chassis. With the hair-line brushed anodized aluminum finishing and its intelligent multi-heat zone design, the PC-X900 fits perfectly in the living room as a home theater system, as well as proving a complete thermal solution to the gamers. Lian Li once again proves its dedications in bringing a convenient and stylish life with the cutting-edge technology and tool-less design to its customers worldwide.

General Features
Dimensioned at 230 x 598 x 388mm (W.H.D.), the PC-X900 is a mid-tower chassis, an alternative choice between the smaller PC-X500 and the full-size PC-X2000 from Lian Li’s product line. Net weight at 8.22kg, it includes three 5.25" optical drives, seven 3.5” hard drives separated in two cages, all with the patented tool-less design. Supporting ATX/M-ATX motherboards, the PC-X900 can hold video cards maximum of 300mm length, as well as occupying seven PCI slots and four USB 3.0 ports mounted on the top cover alongside one e-SATA HD audio port. The TYR PC-X900 is available in red, black and silver colors.

Easy Access & Spatial Design
The most convenient tool-less design is an important key feature for Lian Li’s cases in 2010. Power users’ requirements of building systems faster and swapping the components often have been taken into consideration. This is why the side panel of PC-X900 is transparent, and can be opened easily with the tool-less latch, the motherboard tray can be opened and CPU coolers are removable; the multimedia I/O ports are designed right on the top of the case; and the PCI add-on cards can be assembled effortlessly. When installing the 5.25” optical drive, users can simply slide the drive into the bay and close the mounting bar to secure.

The motherboard is positioned at the middle-level of PC-X900, allowing an easy access to the motherboard and more room for larger CPU coolers. There is also enough room for a 180mm long power supply at the rear of the case.
Cooling Fans & Thermal Solution
Lian Li’s PC-X900 has two heat zones design to have better thermal solution and tidy up internal space. Moreover, the PC-X900 features three and two 120mm LED fans at the front and rear of the case, respectively. The fans cover the whole motherboard so they bring in cold air and remove heat effectively. There are also vents on the PCI slots, providing extra cooling to the graphics cards. The power supply unit is at the bottom of the case so that it can draw cold air in directly through the vent below. Finally, there is a fan controller in the back of the case for users to adjust the fan speed and get the best balance between silence and cooling.

While I dont get the point of this 2 zone system, since optical drives dont produce that much heat. I guess you could put some HD's up there. ....

Yeah Der Meister if I was going to spend anywhere near this amount on a case as the article states I would just go for a LVL 10. I don't like the separate zone placement either where it makes sense to me to have a PSU on the bottom with an intake from there (as it brings in cool air), rather than up top where the PSU is in more heat which has risen up from the components below it. I don't see a top exhaust either which is kind of strange.

Design doesn't impress me in the slightest. The 2 zone thing doesn't do much for me.

Now, gimme a unit that will help me pipe air through my graphics cards without taking main case heat, or heat from the proc, and that's more useful.

I'm a fan of the Antec P18x series and the Viper 2

Yea I tend to agree with you guys on this one even though I am a die hard Lain Li fan. They should have put the PSU and hard drives up top. The only point I see to zone 1 is to keep the HDD seperate but with SSD's becoming more popular I don't even see the point in it. Me personally, I would try to somehow change the entire Zone 1 into a huge resevoir or something. That would be cool huh!

I have a two zone case. PSU and HD's on the bottom level. Mobo and everything else up top...

They do make some pretty neat cases. They are really pushing for sales lately.

It really does seem like more and more we are supporting Taiwan's economy!

I think they took a step in the right direction here. One thing you guys are overlooking is the fact that none of the zone 1 clutter is in zone 2. I think the reason we have this bizarre heat divide is that the mobo and hd's get straight up cooling. There is no "wall" blocking the intakes. However, as mentioned, the HD's seem oddly placed and I think they will actually interfere with the cooling of the case. I would put them in the rear of the case, with a fan pushing the air out, with a dedicated intake from the bottom of the case. This could be directly piped to the psu for the outtake. These types of cases really make me want to build a case of my own and to experiment with some ideas floating around in my mind. Additionally, there is no way all psu's will work in this case.

[edit] After re reading what I wrote, while looking at the picture, this case is terrible.  This case would cause more clutter than necessary, the cables would be everywhere.  However, I do think they're onto something but they need way more work to fix it.

^move it to the bottom or put the PSU in the zone...
