I had a similar issue and even after some extensive carving, I still had the top right side of my board (the one that wraps fully around the standoff) not fitting correctly. I was able to apply some pressure to the board to get it into place and I essentially locked it in with an expansion card.
This is the 2nd mainboard Cooler Master case I’ve built the first one did not have this issue.
Thank you!! This just saved me a ton of time waiting for a new case to come (time I don’t have). I greatly appreciate it :))
As an aside, I’m very disappointed in Framework’s QC. This is the third time they’ve sent me a defective product–the first was my (11th gen) laptop with bad hinges, then a bad ethernet expansion card, and now this case; every single order I’ve made since their founding has contained at least one defective part.
Framework Support made it right every time, but I have no clue what’s going on with them… their inability to consistently ship quality products is not a good look. End rant :,)
I just received my Coolermaster case, and have the exact same issue. Like @blakeslee I’ve received defective parts every single time I’ve ordered something from Framework. I keep giving them extra chances because I believe in the mission of repair-ability, but at a certain point the odds just don’t add up anymore. Framework has significant quality control issues.
My original laptop came with the webcam module installed incorrectly. A defective touchpad. And I’m now on my fourth set of hinges. And now I receive a Coolermaster case that doesn’t fit the mainboard it was designed for. 
Framework, step it up.
Looks like the case I received has the same problem described in this thread. Is this a Framework problem or a Cooler Master problem?
Framework support sent me a replacement case, and it arrived today. Exact same problem. Motherboard doesn’t fit because the white plastic from the bottom case is too high and prevents the motherboard from sitting on the black pegs.
I just can’t fathom how Framework’s failure rate is so high.
Hi Daniel,
Sorry to hear that your replacement case has the same issue, I’ll be sharing the feedback internally so they can share it with Cooler Master.
Just received my third case. Framework offered “whiteglove service” for this, meaning they had someone visually inspect the case before shipping it.
This one is definitely better, but the motherboard still doesn’t fit safely. The motherboard sits too high. I can just barely install a module if I apply downward pressure on the usb port, which I wouldn’t even be able to do if the case was closed The case doesn’t close, because the motherboard doesn’t sit low enough.
Has the framework team actually tested these with Framework motherboards. Because it’s pretty clear to me the design is incorrect.
I’ll send photos when I get home from work.
This is absolutely the last time I send Framework a penny until there are clear and public statements on how they’re going to address quality control.
I’ve given Framework way more chances than I would have given to any other company because I believe in their mission on principle. But with such terrible quality control theyre worse for both the user and the environment than just buying a generic non-repairable system that will just work for a few years without constantly replacement parts.
Here are some pictures of the THIRD case I’ve received. This one they claimed to have done whiteglove service, meaning an employee inspected it before sending.
This is the best of the three cases I’ve received so far. But this one still doesn’t fit the motherboard. The usb ports don’t quite align and the case will not close.
I’m also just now noticing that all of the photos on the store page show that the case is black. But all the cases I’ve received and seen here are white.
I don’t care much about the color. But that does raise a concern about false advertising, and that the switch to white is potentially the cause of the issue since the white plastic overflows onto the black plastic pegs.
I finally decided to 3D print a case, and it fits perfectly. Don’t bother with the Cooler Master case. They’ve clearly got a bad batch, and instead of doing anything about it they’re just repeatedly sending out defective cases.
People are complaining about this on Reddit as well. There’s another user on there who like me has already received three defective cases.
Still waiting to hear back from support on the third defective case.
I have the same issue!
Yep, I also had the same issue. Fixed it with a knife.
After reading all of this, I wouldn’t be surprised if there’s an entire batch of bad cases.
I had the same problem. I whittled down the base of each screw post with an xacto-knife to whittle away the cone shape down to a straight cylinder with flat step at the base. Got my case a month or two ago.
I returned the three defective cases I received and got a refund. I appreciate that Framework’s customer support has been helpful through this, but still severely disappointed in the quality control.
I’m also disappointed that they’ve ignored my comments about the actual case being a completely different color and design from what’s advertised on the marketplace. The marketplace images are still of what I assume is a prototype that was never sold.
Hey Daniel, just to be clear, all 3 of the cooler master cases you have received were opaque white, right?
Thanks!
Yes, the cases I received were all opaque white with a dark tinted top cover. Just like the photos in this thread posted by myself and others.
The photos on the Marketplace all still show a black case with a fully transparent (not tinted) top cover. I tried bringing this up during my correspondence with customer support, but it was not acknowledged.
Edit: To clarify, the color was not a factor in my return decision. Honestly I think the actual design is nicer than the one on the marketplace. But the marketplace listings should be updated so that people know what they’re getting.
Thank you Daniel, the support team must have missed that one (and I personally missed it because my brain could not register that it’s transparent) just shared the feedback internally. Thank you for sharing feedback even after returning the product, we have shared feedback for the quality issues you have reported as well.
Same issue, cannot fit motherboard into a case, and i dont want to destroy anything.
Looks like common problem, Framework, any thoughts? is this batch problem?
I have no time for replacements now i need this device here and working so i guess i will have to do manual fixes 
Same issue with my recent purchase. As I had already stripped screws getting the case apart, I figured I would never be able to return or exchange it, so I just fixed it myself using a set of fine files/rasps and a little help from a dremel on the lowest speed setting.
The key was getting the underlying plastic under the posts to be the same thickness as the metal posts, so that the holes in the mainboard will be able to slide all the way down. I also had to trim all the plastic slop that crept above where the posts met the plastic. It doesn’t look great, but it’s not in a place you can see once the mainboard is installed, and I was able to get all four expansion slots to line up with the case slots.
Thank you for forwarding it to support. It looks like the images on the marketplace have been updated 
Yes, it has taken us some time but we finally updated them, thanks for letting us know
