Ok, I is happy now. I can has pics.
Children not allowed - naked Mac Mini below!
I stripped the Mac Mini once again to get inside and see all the good stuff, not just for the looks of it but definitely also for making it even better!
In there at the bottom you will find a PCB looking like this:
There is a thing about this PCB you should notice if you want to change the heatsink - there are some very very tight clips holding the original heatsink in place that are close to impossible to get out:
I cut them off and got this little beauty to look at:
The Intel Mobile Dore2Duo T7200!
It's by now more than 2 years ago since it was out in the air last time.
Can't really leave the surface of the chip like that when I have by now spend somewere between two to three hours on preparing that heatsink (can tell that copper is NOT the easiest to cut by hand, oh my God!) so had to clean the bad boy up:
Only one thing I wanna say now: "My preciousss!!"
Mounting the heatsink was not that much a hassle:
Only thing you should notice here is that on the original heatsink there is a lump cut into it that matches the size of the thermal probe perfect, mine does not have that and I have no way of making so.
So I had to mount the probe as close to the heatsink as possible, sticking it on there with some "thermal cement" (or what ever you would call it, look in a earlier post about a product from Koolance).
As you might also have noticed, the plastic screws came in handy once more - as stabilizers for the heatsink!
Backside of the PCB once again were the nut sits in place tighly
Before we are getting to the part were I tell about why I call this chapter "Let's bake!" then let's talk airport!
I have as some might know by now bought a AirPort express 802.11n card from a MacBook in China over eBay. NOW is the time to put it in!
Aaaand there it is with all it's glory of three antennas, MIMO-style!
Back to the title...
The mini is build like a cake, it's layer upon layer.
At the bottom layer you have the north bridge, the controllers for USB, FW, DVI and every other port on the backside, you have on top of that the CPU, GPU, RAM, AirPort and so on.
Next layer contains HDD, fan and speaker, on top of them comes the optical drive, the antennas for BT and wifi and then comes the top and closes the thing off as cream on a cake would do it.
A problem by that structure is a thing I noticed last summer when it was extremely hot here in Denmark, my mini was about to get completely cooked!
Reasson? The northbridge of all things was boiling hot!
There are absolutely no way air would ever get to were that chip is placed, so Apple have put a tiny thermal pad in there to make so connection between the metal bottom and the chip, to by their intentions help it keeping the head cool - but it does not really work that well...
My idea is to close up that space there is between the bottom and PCB with a material made for being cooler than air would be under the same conditions, a thermal cement like product made by a company called Koolance seems to be the proper thing to use.
Read more about it earlier in the thread.
Enough talk, let's mod!
Even here you see why I titled this one "Let's bake" don't you?
It's Koolance and some thermal paste, ThermalRight Chill Factor.
On the CPU by the way I used some IC Diamond 7 paste, high-tech and should be one among the best there is.
Before closing the cake and put the cream on I would have to mount the two extra antennas for the MIMO effect on the new AirPort.
I have seen examples on the web about how to do this by routing the antennas out the back trough the Kensington lock hole - but what if I some day need to tie it to something with a wire, then I would break the antenna... Not ideal... I want them inside and unseen!
One goes at the side (original Apple part), the other goes at the top because it's not an original Apple antenna (the orange one in the corner of the pic) it is super slim and fits perfect up there - and of course I reused the original AirPort antenna too, no need to invent something that already work.
Almost time to close it up but need to change the light of the front diode first.
Again the UK came me to the rescue, only place I could find blue cellophane was on Amazon!
A tiny piece of sticky tape and I got a blue diode
This is actually the end... I can't show you for real how awesome it looks, mostly because I don't have any green sheets of paper witch I would love to have for taking pictures without distracting reflections. But that's just a matter of time before I get some and let you see what a beauty it is
Anyway, here's a tease:
Remember I said something about I got an idea when I took a picture with the white outlined logo on top but forgot the flash?
Here it is, the idea:
Sure, I have'nt found the perfect vinyl yet, it got bubbly after it had been on for like a day, when I first applied it it was smooth:
I can live with it, it is supposed to be standing in the shade were my stereo system will be when I got that part assembled. It's like listening to music and be able to relax because you completely forget the system that is playing and just enjoy the sound. I don't want to see the tech, I want to use it to the max though!
By the way, the logo on top is shinny silver, just like the one on a Time Machine
Talking about Time Machine, I just bought a AirPort Express so I can get something to use the fancy new AirPort card for, 802.11n
With and without
With and without light (see the blue diode!):
And that's why I say I can live with it, when I'm here in my "cave" it's usually with dimmed lights - either for doing graphical work on the screen, watching movies or listening to music.
Only times here is bright light is when I need to clean...
very, very, VERY nice!
I am impressed, great job! Would love to have something like this.
good job, shame about the vinyl but you can worry about that on a rainy day!
Sweet sweet sweet
Would look nice on one of my shelfes
Den er fandeme blevet flot.
Jeg kan forestille mig hvordan den ser ud irl.
That's really cool mate, nice one.
Tillykke med den - danish modding Cheesecake!
DK-Modding goes mini
Exactly my point
I have to say i find the stands a bit too big for the mini's size. but no point in saying that now that it is finished. i like the black finish of the body, though. looks nicer than i thought it would.
Wow, so clean job. I love that kinda of cases ;D
Light bulb moment - anodize a case and give it a weathered dry brushing in a different colour. Hmmmm....cheers for giving me an idea dude
I kind of agree, the stands are big - but soon you will see why I chose them, they are the only ones that match the look of those underneath a NAD C165 pre-amp (which I hope will arrive next week).
Anyway, thanks for the response
Always happy to passively help others
I can for sure recommend Computer Choppers, they can do the most impossible to computer cases
See much more pictures @Flickr (and without the watermark )
So what do you think now?
