My first build attempt has been an absolute nightmare. Please bear with me as I try to summarize and illustrate the main problems.
I started buying parts in February. It took me way too long due to some indecision with choosing components, waiting for sales, or just being busy/distracted. Regardless, here's my parts list.

I put the PC together yesterday. After installing the CPU, CPU cooler (Hyper 212 Plus), and RAM on the motherboard (Gigabyte z97X UD3H), I prepared to mount the board in the case (Corsair 300R Windowed). The 300R has a built-in alignment stud in the middle, and the standoffs are integrated with the screw holes. Anyway, after putting in the I/O shield aligning the motherboard was a challenge. One of the screws (#2 in the picture below) didn't align properly. The motherboard is apparently not the full ATX width, so you can see 3 screw mounts off to the right of the board.
Note that the numbers assigned to the screws are arbitrary and don't reflect the order they were tightened. After getting the alignments and setting the screws I tightened each one gradually ~1-2 turns at a time (except #2 which couldn't go in very far due to misalignment).
In order to get #1 to line up I had to apply slight force from the top right (near the RAM slots) toward the I/O shield. 3, 4, and 5 aligned without trouble. Here's a shot of hole #2 w/o a screw, after the other four were inserted.
I was concerned about bending in that area of the board, so I decided to just put that screw in as far as it would go (no excessive tightening or anything) to provide a little support.
I can confidently say that it simply was not possible to align #2 properly. Here's what the other four screws look like.
Moving on, most of the remaining assembly was okay but took awhile with the cabling and connections. It's just incredibly scary when you see the board flexing as you insert or remove connectors. The ATX power connector was especially a pain. After getting everything but the GPU (XFX R9 390) installed, I decided to boot and make sure everything was okay in the BIOS. To my relief everything looked okay - all the components detected, the system fans and CPU fan both working properly and showing real-time speed changes from PWM, etc.
So I turned off the PC, switched off the PSU, and improved some of the cabling in preparation for installing the GPU.
In a nutshell, the GPU just doesn't fit. The card doesn't line up with the PCI-E slot - there's something like a ~1-2 mm offset. I tried to take some pictures but it's difficult when holding the GPU.
That's as far toward the rear of the case that the GPU goes. I don't know how much of that is due to the motherboard alignment. Recall I had to get the holes (1 and 2 in the above pics) along the "top" of the motherboard aligned by applying slight force to the case rear, but the holes on the "bottom" of the board (3, 4, 5) didn't have trouble aligning.
Here's a better look at the gap between the board and the rear of the case.
In addition, the plate on the GPU is not square, which would cause issues in aligning the GPU to the PCI-E slot while also getting it flush with the back panel.
And the tabs on the plate are also bent (from some google searches this seems to be common?).
I also tried putting the GPU into the x8 slot, just to test if it fit, but had the same issue there. I didn't try to force in the GPU because as you can see from the pics the alignment simply isn't there. Just to note, I did remove the covers from the GPU ports which might have interfered with aligning to the rear bay.
Summary
I can't fit my GPU into the PCI-E slot. Don't know if it's due to an issue with the motherboard, case, or GPU itself (likely a mix of all three). If the motherboard is too close to the rear of the case for the GPU to fit in the PCI-E slot, I could try to loosen the motherboard screws and see if the GPU fits. Even if that worked I highly doubt the motherboard would mount to the case as demonstrated above.
I've read some discussions elsewhere of people having resolving similar issues by fixing the GPU plate bending themselves. Thing is, if I bent that retention/port side of the backplate to make it perpendicular to the long axis of the GPU board, it would probably make the slot alignment worse. So that makes me wonder if the motherboard mounting is the main issue. Or the case having offset mounts. Or the GPU plate actually being the main problem.
I'm incredibly frustrated and demoralized right now. Spent all day yesterday assembling the computer. It's my first personal build but I've helped others before, and I've taken apart laptops plenty of times to replace components, repaste, etc. so I'm comfortable working in a PC. I took things slowly and made sure to follow instructions and not get ahead of myself. Since I bought many of these parts more than a month ago, I can't return/exchange things like the GPU if the plate bends are the main problem.
If anyone can help advise me on this I'd really appreciate it. I'm not sure what to do at this point and it feels like I'm completely fucked with everything.
