GTX 560 Ti not fitting into Antec 300 case

Hi,

I'm trying to build my first gaming PC. Everything's gone good so far except when I tried installing the discrete GPU.

GPU: EVGA GTX 560 Ti Superclocked
Case: Antec 300
Mobo: Gigabyte Z68A-UD3H-B3

Here's what happens: The GPU aligns fairly well with the PCIe-x16 slot and the end opposite the back panel even goes into the slot. But the back-panel-end refuses to fall into place because the metal tab at the bottom of the panel is not fitting into the metal gap at the bottom of where the PCI slot cover used to be. I removed adjacent slot covers too to make sure nothing was interfering. But it's almost like the metal tab at the bottom of the panel of the 560 Ti is too thick to fit into the gap in the chassis.

How do you fix something like this? How do I figure out whether this is a problem with the GPU or the case? (or my incompetence?)

Thanks.

I was initially unsure whether the tab had to come out of the case - but examining it closely suggested it is supposed to. And no, this is precisely what is not happening - the tab is blocked such that it cannot come out of the case.

also might help to visually compare the video cards slot cover to the one you removed from the case. you can also try putting the old slot cover back in the case and wiggling it around a bit to slightly pry the sheet metal apart.
 


That is my perception of the problem too. But, it is most unusual to have standard parts that mismatch like that. A pic of where the parts miss might lead us to the guilty component or a solution.

Splendid

There are no mismatch, it's probably OP's very first build so they're not familiar or are afraid to break something?
OP can do is bend the tip of the graphic card a bit and it will fit.

I'm sure most of us during our builds have encounter this problem including me and the poster (Inzone) above.

Oh motopsychojdn, you made me think for a moment that I didn't install standoffs. I panicked, took the whole thing apart only to find out that I did install them.

What lp231 describes with that picture is entirely accurate (no picture I attach could clarify things beyond that).

So I have two options now -
1) Bend the tip on the GPU backpanel - this scares me much, esp. since it's a tip with $250 worth of equipment attached on the other end

2) Somehow remove the metal of the slot so that it doesn't get in the way - I'm not sure how I can do this

In any case, either the GPU or the case has not been built to standard. When my PCI Wifi card arrives, I should be able to tell which it is.

This *is* my first build and having to bend metal on a GPU is not something I expected to encounter.

By the way, the metal tab at the end is already bent (by the manufacturer) at a very shy angle - just to confirm - I should bend it slightly more (with what? a plier?) away from the card... right?

If by mounted correctly you mean:

1) Golden standoffs screwed into holes in the chassis
2) Motherboard placed over the standoffs so that the screwholes in the mobo coincide with the standoffs
3) Screws screwed into motherboard screwholes all the way into the standoffs

.. then, yes, I'm 100% sure the motherboard is mounted correctly.
 
It may be there is an error in the pressing of the case , but I technique can help .

When you install the card slip the two metal tags into place FIRST and then gently rotate the card in to the electrical socket


If anything does need modifying I would mod the case , and stay well away from the graphics card

That's what I tried first but the fact that the motherboard is raised by the standoffs makes this futile.




This is what I'm thinking I should do now. I would have to file off a piece of metal from the case.

Again, waiting for that wireless PCI card to know whether I should be writing an angry review for Antec or for EVGA.
 
The tip of the bracket should be straight don't bend it any more straighten it.It might be bent too far forward. Alternatly you can take the tip of a screwdriver and put it in the metal part of the case where the bracket tip goes and make the slot slightly bigger.

Are you sure about that? If I straighten it, the tip of the bracket is going to be further inside the case. At the moment, the tip is just resting on the inner edge of the slot. Which means if I bend it outward (hypothetically speaking), away from the card, it would stop resting on the inner edge and fall into place in the gap that's just outside the chassis.



Trying this at the moment after removing the mobo again.

Ok - managed to make it big enough so that it has at least slipped into the slot. But it still hasn't gone all the way in - at least not enough for it to fit into the PCI slot and definitely not enough to be able to put a screw in the bracket hole. Increasingly starting to think this is something terribly wrong with the build of the case.

Gah - it seems impossible to do this without removing the metal tab. I've decided to file and remove the obstructing tab. Being such a noob, I'm going to have to order a file set (http://www.amazon.com/PIECE-MEDIUM-SIZE-DIAMOND-FILES/dp/B000UCREE8/ref=sr_1_1?ie=UTF8&qid=1315981961&sr=8-1). Does anyone think this is a bad idea / not the best solution?

Thanks for all the help so far btw.

So close to an awesome gaming machine. Just one metal tab away :(
 
I'd file the case, definately not the gfx card but hey,
welcome to the world of Modding Bro :)
Still at a loss as to how/why this is even necessary to be honest, manufacturing variances aren't usually problematic to the point of non-function,
and you'd be surprised how many folks forget/dont know about standoffs, I had to check mate
