Apple makes Mac Pro with a very elaborate design, not only to make the product beautiful but also has many features. In addition, Apple was forced to take care of its professional computer to not be told to neglect the "pro" market after the 2013 Mac Pro's failure.
Frame and cover
From the outside, looking at the Mac Pro is "dominated" by an aluminum case, which stands out with the handle and the base protruding out of the rectangular frame.
At the top there is a circular lock, which will help separate the casing from the frame, but it also acts as a handle for you to pull the case up more easily. After peeling off the cover, you can see the internal components and replacements, adding what you need. There are no screws, no rough shackles, the opening is very delicate.
The case is made entirely from CNC lathe, it is sandblasted and aluminum plated, this part is made very hard and can stand on its own without frame. The front and back sections are cut open for ventilation, this one we will discuss later.
Actually, this is not the first time Apple has used this design. From 2000-2001, the Power Mac G4 Cube also possessed similar shell openings. You can see the picture below that is immediately relevant.
The heat sink design of the new Mac Pro was also inspired by a predecessor: the Power Mac G5 (boxed version) launched in 2003. It is often called funny cheese.
The G5 is divided into 4 radiator zones with plastic walls. Each zone has a slow fan to draw air from the front of the machine, the air passing through the device cools them and the hot air is pushed out behind the case. At the time of 2003, this radiator design could be considered "revolutionary" when most other tabletop cases only used 1 large single radiator area, less effective than G5.
Separating the space into small areas allows controlling the temperature of each area and cooling is independent of the rest. Fans only spin when one or more components are hot, not spinning all the fans in the tank, resulting in a quieter cooling system and more efficient cooling.
In the new Mac Pro, Apple uses a piece of metal they call "Sea wall" with the motherboard to divide the Mac Pro interior into two heat sinks. In the larger chalk in front of the board, three large fans will suck in the cool air, the air passes through the CPU radiator and expansion cards before being pushed out at the back.
On the other side of the mainboard, there is a smaller fan that draws air through RAM, SSD, power supply and push back.
$ 1,000 stand of Pro screen Display XDR is designed to comfortably move the screen angle, in any direction and direction you want, thanks to a flexible "arm".
In fact, since 2002, Apple has been using this footprint design on the iMac G4. This is the first iMac to use a flat screen and it has an arm that says a screen with a body. This arm is so solid that Apple says you can use it as a handle when you need to move your iMac.
Radiator hole design
The design of these holes is completely "controlled" by the features Apple wants. It solved the problem Apple had when they made the MacBook Air and MacBook Pro unibody in 2008. How can you cut almost everything on a monolithic piece of metal without breaking its structure? (In other words, make it easy to break, break).
At that time, Jonathan Ive shared: "This part of the palm rest is the backbone for the whole product. Normally, when you have a projection for your hand, you will cut a large hole and make the piece of metal no longer firm in texture. We discovered that instead of cutting large holes, cutting many small holes would make the structure of the metal piece almost unaffected. "
Basically understand this: instead of cutting the MacBook's aluminum pieces and cutting a big hole to place a large keyboard (like the old Macs), now you cut a lot of small holes and put each key. The rest of the metal is still strong enough and the rest of the mat is also very hard.
The way to deal with the Mac Pro ventilation holes is similar. Apple uses a spherical grinding head to cut away the excess aluminum on one side, and do the same from the other side. This "3D" cut allows air to flow more easily between holes. This process removes more than 50% of the material while ensuring a sturdy case.
And to pick out the depth of the cut, the overlap between the round end of the tool, the ratio of the diameter of the sphere to the surrounding space, and the air flow optimization … it must be that Apple has to experiment very well. Many times, it will be the last convenient configuration.
Cord covered with fabric
Usually the accessory cable of Apple accessories will be covered by a rubber-like plastic. With the Mac Pro and Pro Display XDR, Apple uses a cloth-clad cable for both the power cable and the Thunderbolt 3 cable. Perhaps it does so to increase durability. HomePod is also a fabric-covered product.
The keyboard of the Mac Pro is different, it is not pure black or white as it is, but it is a silver-white hybrid with black. This color looks better and more beautiful.
Finally the wheel, the new Mac Pro can mount wheels to move between work areas, studio rooms, studios …
