My 2012 iMac has started its journey to Silicon Heaven, and pretty soon it will be no more. I found a lot to like with this machine, but I have been growing increasingly frustrated with the lack of user-serviceability.
Can I replace it with a DIY PC that is at least as powerful? Can I do it for less than a new iMac would cost me?
That's what I plan to find out, and I will document my progress :)
Specifications of the new 27 inch iMac as of February 1st, 2018
At the time of writing, the not-too fancy iMac 27" looks like this.
That's $2,399 CAD for an all-in-one 5k unit, with an i5 or an i7. Fusion or SSD options. Keyboard, mouse. Yada.
Here is what I am replacing:
Pretty humble by today's standards. Note the graphics especially.
16gb RAM and SSD puts price up
Selecting 16gb and SSD on the entry-level 27" puts the price up by a lot. I am optimistic about this budget.
Now, of course, I would love this machine to be a "Hackintosh" (IE. install Macosx and have it work), but I am comfortable enough in Windows or Linux that it's not a dealbreaker.
Going Modular
Right off the bat, I save money by not going all-in-one.
- Cheap-ass case - $30 CAD!
- Cheap-ass motherboard - $65 CAD (there were cheaper but I wanted at least 3x PCIe slots)
- 4k monitor - $467 CAD (I don't need 5k, and I can always upgrade later)
While I loved the aesthetics of the iMac, really it was also the cause of my frustration. I need to go modular so I can switch parts out.
Going DIY affords me maintainability, but it has to be said my Apple gear has always been long-lasting. Our 2006 white Macbook is still running fine and is still in use. Remains to be seen how the ROI works out over the lifetime of this new guy.
Processing and Power
Matching the new mac pretty much, I over-paid, shopping on Amazon.ca, but I bought an i5-7600. In theory, this bad boy can do 4ghz.
I also grabbed 16gb (2x8GB) of DDR4 DRAM 3200MHz memory. Suppose this is better than what is listed on the mac, but in actual use who knows. Expensive stuff.
Interestingly, the included graphics should be out of box macosx compatible and exceed the performance of what I have on board now, even without adding a GPU. That said, I have a couple of GPUs coming, both Radeon and Nvidia, so I can experiment. GPUs are a lot of money right now due to crypto mining, VR/gaming and manufacture supply issues.
The PSU I bought is a touch over-powered at 750w, but that gives me the most upgrade potential. Likely I spent twice what I could have gotten away with.
Finally, one of the failure points is the hard drive. Currently, I have a hybrid 1tb, but for this new machine, I am going to go with Samsung 850 EVO 500GB 2.5" SATA III Internal SSD for booting and apps. Data will be on externals I already rely on, and a secondary to be chosen later.
That's the end of part 1
Now I wait and collect the parts as they arrive over the next few days!
As I said, I likely overpaid by going to Amazon.ca for everything, and by going into the city big box stores I could have had the stuff in my hands right there and then, but by going this route I at least make it more doable for anyone who wants to replicate my experiment (or mistakes!).
Stay tuned ...
Replacing an Imac isn't that hard of a feat. I think I have an old coleco sitting around you can use ..
Love it, though I would prefer to get my old Vic 20 back. I miss that guy :(
lol, now we are talking
If you plan to game on it, you are going to love the difference a windows machine can bring. Also with a price budget of 3500, you could build probably 2 of the most powerful pcs available for the price of the one mac lol. I would suggest going for AMD as it is cheaper and handles shaders better than intel. They are also cheaper and faster. You can get an 8 core with heavy lifting power for 3 or 4 hundred. I am a professional computer tech if you need any support feel free to reach out to me and I can help you out.
I have two of these, could share one with you for half the price you are putting in now :P
But to your configuration. In the example iMac you put in a 1TB SSD for the overall price, while you put a 500 GB in your new configuration desktop PC. That is quite not comparable price like.
Yep, I haven't done the final price and parts list yet, don't worry I won't try to pass off worse things as better :)
Haha I wasn't worried, but I was like this: "Hey, this is cheating!". I mean even if you put in a regular 1TB SSD in your new PC configuration it will be much more cheap then the Mac 1TB :)
Oh yeah I am sure :)
My plan is to have an SSD for boot/apps and a spinny one or two for data. My guess is can do a RAID of spinny HD for price of a reasonable sized Apple SSD ;)
This is so dope! Keep us updated on progress please
Can I replace my iMac with a DIY PC?
Me: OF COURSE MATE :)
Let’s hope you are right ;)
or a gaming desktop or laptop is much more cheaper than apple
i am excited and impressed to see your post..... i waiting for your next post....i wish for your best of luck brother

u can make one of the best gaming rigs for that price or even cheaper and it would be way more powerful than any apple product
agree :)
For gaming forget about it brah. Moving from an iMac with a mobile graphics chip to a desktop PC with a discrete graphics board is like swapping your moped for a Porsche. If you're a little morally flexible you can install Mac OS X on certain brands of motherboards too and build a Hackintosh. Dual boot into Windows 10 or OSX.
I have a licence for macos so I'm going to try it
