السلام عليكم....
اولا نورتوا الموضوع...
ثانيا بالنسبه للتكلفه فى اعتقادى ان ارخص الموارد هى الخشب وهذه الكيسه لا تتطلب كميه كبيره من الخشب ....
بالنسبه للأمان فى الإستخدام ودرجات الحراره اترككم مع اجابه صاحب المشروع...ولا ننسى انه يستخدم التبريد بالماء ...
Measurements
Temperature
It has been speculated that wooden cases could easily catch fire. Birch wood catches fire at around 500 to 700 celsius. Unless a very critical accident occurs, I'm certain the case is safe.
I did some measurements of temperatures from the new wood case and the old * * * *l case. The processor temperatures were taken to show that the case couldn't affect them. This is because the processor is water cooled, and the radiator is outside the case.
Inside the case, in 25 celsius room temperature:
Old case: 36 New case: 35
Processor, watercooling system, full load:
Old case: 40 New case: 40
There have been claims that * * * *l cases are cooler than wooden ones because * * * *l dissipates heat, while wood is an insulant. From these figures we can conclude that case temperature is affected mostly by airflow and the heat generating components. Since the old * * * *l case and the new wooden one both have adequate airflow and the same components, the temperature has not changed.
Weight
In several forums I've seen arguments that wood cases weigh a lot compared to * * * *l cases. By itself wood is a very light material, what makes it heavy is that it must be thick. To make the case sturdy and noiseproof I chose to make the walls of two centimeters thick. They could probably have held together just as well with thickness of 1.5 cm or 1 cm.
The wooden case weighs a bit over 10 kg when it's empty. My old * * * *l case of similar size weighs 8 kg. Both cases are heavy and difficult to lug around. I wouldn't recommend a full tower wood case for someone who needs to carry the computer a lot. If weight is an issue, you could do much better with plexiglass.
Noise
I don't have a decibel meter at hand, so I can only give an assumption on how much noise the new case generates. Whereas with the old case I couldn't sleep with it on, I can sleep right next to this one. Using a 12 centimeter fan with barely minimal rotation speed means there's virtually no noise from the case fans.
The most audible part of the whole computer are the hard disks, which produce a constant humming noise. While their noise is considerably dampened by the wood walls, it is by all means still audible. To further silence the case the hard disks need to be noiseproofed separately.
If you are looking for a silent PC, then wood is the way to go. The case doesn't echo or rattle. Wood itself will not make a completely silent PC, you will still need silent hard drives, a quiet power supply, and most of all a noiseless CPU cooler.
Final words
Building the wooden case was a major undertaking. It took me nearly half a year of spare time to complete it. I didn't count the hours, but the total must be hundreds.
As you can see, the case looks really good. I'm very satisfied with the craftsmanship, and there are no major design faults. Besides the looks, the quietness, and the handy side panel, there are no real benefits to most other cases. It is after all just another box that houses my hardware. A good looking box at that, but a box nonetheless.
