    Zalman is not normally known for their cases, but they are looking to please gamers everywhere with their Z-Machine GT1000. With it's black aluminum frame, the case is built like a tank. But is it worth your $400?

    The airflow design of this case is terrible. I don't like that the side panels aren't completely removable. And it's kind of small.

    IMO, this case is barely worth $100.

    Hehe, I loved the "Built like a Tank" pro. That made me chuckle like one would at Jack Nicholson in The Shining when he says "Heeere's Johnny!"

    I don't think there is enough room for an 8800 GPU in there.
    These people designing cases should consider what gamers need.
    92 mm fans are louder than 120's

    Airflow design in this case isn't ideal, but our hardware never reached an alarming temperature... not once. It's a mid tower and to compensate for the complete lack of hard drive space in the Fatal1ty was to add an extra slot on the front cage. Again, it's a mid tower. There aren't to many cases of this size that are going to win any awards for airflow design. Shit is going to get cramped. Perhaps if they kept the hard drives parallel with the motherboard the air would be a bit less restricted.

    As for the doors being removable, I honestly didn't have any hindrance at all with the doors pulled open all of the way.

    As for the price, no, it's not worth $400 to anyone but the most avid fans of either Zalman or thick aluminum.

    It would have been difficult to place a pair of 120mm fans side by side in the front, defeating the intended look of the case entirely. And concerning what gamers need, they sure as hell do not need a $400 chassis. This is a novelty luxury item, well out of reach for most but we weren't going to give it a 5 score for being expensive alone. As for an 8800 GTX fitting in there, I do not have one on hand to test this but it would be quite close if it fit at all.

    I agree that the price is bordering on asinine. I can vouch for the quality of the case though. I was at Greg's house when he first received it, and even saw him squeal like a girl when he first took it out of the box.

    Very solid case, I love the look of it, but I dislike the lame "Z-Machines" branding, and the price could have been less luxury.

    Haven't read every post yet, but an 8800 GTX or Ultra fits fine from what I've seen of other screenshots. Tight fit, maybe a half inch between the end of the card and the drivebays, but will fit.

    Even if your hardware didn't reach high temps it's just because your room temp wasn't hot and/or your hardware wasn't highly OCed or much OCed at all. The airflow design is not just not ideal, is terrible. There are MANY mid tower cases with much a better cooling design. This one not only has one intake and one outtake (counting the two front 90mm fans as one intake), the HDD cage blocks the front intake completely. I don't like having to remove it and limit my HDD space just because their flawed design. If the front fan was replaced by a 120mm fan and the HDD cage was set with the side parallel to the side of the case, then the airflow would be ok. Even if they left the 2 x 90mm fans, but at least turned the cage 90 degrees, it would be ok. But they didn't,tsk tsk.

    As for the side panels, I like laying my cases flat on the side to work on them. I would hate not being able to remove those doors on the side.

    The least of my worries about a case is how much thicker the aluminum is. It's an nice bonus to have it thicker than usual, but easily sacrificed if it means paying much less.

    Even if this is a novelty luxury item it's still way overpriced. They didn't make the novelty luxury item well, they certainly didn't make it worth it.

    TEXAS!
    I appreciate the fact that this thing has a hinged door... and that it doesn't have any hinged parts to the front facing side. (I personally hate those)

    That being said, I have but one word left for this case, ugly.

    Not really. The air leaving the hard drive is barely heated and then trying to cool anything else would be almost as efficient as if the hard drive didn't produce any heat at all.

    If you cool something you are taking away heat, the heat is absorbed into the passing air. Ambient in say, 80*F across the heated hard drives, picking up heat thermals. The abient air is now layden with heat from hard drive/s. That air passes over the GPU. picking up more heat and so on. The total heat exumed from the case is the some of all heat inside the case.
    What I'm saying is that ambient air changes it's temp as it collects the heat inside the case. The flow is first in contact with the heated hard drives ( do you know the operating temp of most hard drives? ). Then. let's say it picks up only 10% of the heat from hard drives, So ambient air that was once 80*F is now 92*F, then it may flow around the GPU and pick up less amount because the humidity in the air can only hold so much heat. Adequate cooling is achieved when air absorbes heat at a certain airflow rate, slow to medium is best due to the time the heat transfers to the cooler air ( heat is absorbed at a certain rate with the temp/ humidity from the ambient air.
    By the way, I worked in AC and refrigeration for ten years, so I know how heat transfers.

    Yes, I know how heat transfers too. I was in Engineering for 5 years. Yes, the air will be hotter than outside the case, but trust me, from the HDD to say the video card, the air will barely be heated compared to if the HDD didn't put out any heat at all. The HDDs don't put out that much heat and the air will be moving pretty fast. The temp of the air from the HDD cage to any other component won't be affected much by the HDD. The air will be heated up a little bit, but just a little bit. Not really enough to complain about its efficiency difference from passing over/under the HDD or not. Especially if don't have low room temps like me. Of course, if you happen to have like 3 or 4 Raptors crammed one on top of each other in front of the fan then in this uncommon situation the temp difference will be much more noticeable, but unless the situation is something of that sort, there won't be much of a temp difference.

    PS. Slow or medium airflow rate is not best. You will cool the object faster as the airflow rate is faster. Which is the reason for low, medium and high settings on things like fans. If you're still too hot with the medium setting, the set it to high for a faster airflow rate and more cooling. Let's say you have an object that outputs heat constantly and needs active cooling like a computer part. The faster the airflow rate the cooler the air touching the hotter object will be because the heat transferred from the object will be carried away quicker leaving less time for the object to heat up the air that is at the moment touching it, hence more heat will transfer from the object trying to equate temperatures between the air and itself. If the airflow is slow the air touching the heated object will obtain more heat before it passes by, so eventually the temp difference between the object and the air won't be as big as the difference between the object and the faster moving air, hence the stable temp of the object with slow airflow rate will be higher than stable temp with higher airflow rate.

    LOL....Okay I see you DO know about thermal conduction of air.
    Just remember the humidity to temp relationship.

    Peace,
    Merlin :eek:)

    PS..... I designed resturant capacity ratings

    Some buildings are like a computer case, and in a resturant you not only have cubic feet to cool but many other devices that give off heat.
    Everything has a BTU rating that resides within. So you have to figure the BTU capacity for all the equipment. Same as inside a computer case, only a smaller scall but just the same.

    Sounds like a fun job. At least for people like me who like thermal dynamics.

    It is an interesting field, I think we could design a better case than this

    Just read your comments on this case, which i own now for 2 months or so. Graphic card is a EVGA 8800 GTX (yes, there is enough space!), 3 GB OCZ Reaper, Asus Commando mobo and WD Raptor HD, Zalman 9700 CPU cooler. I followed this thread with interest and learned a lot from a theoretical point of view. My experience:


    Running Bioshock at 1280x1024 at max details (ok, not the highest resolution, but still...), 3D Max 2006, Cinebench R10 etc. and room temperature at 22° (no open windows etc): GPU temp never over 64° (HL2 Episode 1: 59)°, HD temp around 32°. Fan rotation at 1700 rpm (average). The design can't be that terrible then... i think its rather terrific.

    Whether the case is "ugly", as somebody noted, can be argued... I like the "understatement" look of the case; not one of those cases which seem to have been designed by H.R. Giger himself... But ofc, looks are subjective.
