Any reason in particular that you want to use a V351? To be honest if you're using a A05N its already a very small case. The V351 may even feel a bit bigger because of its cube size.
That xigmatek will fit if you cut off about 1/3 of it. The PSU is also fine for your setup (Looking from the website it has 3 12V rails, which is more than enough for a midrange build)
Check to see how hot the mosfets are. The comp can be unstable if that area gets too hot. Try running a fan over those to see if it helps with the reboot
Maybe you can take a look at the Lian li V350. IMO that case did a pretty good job in terms of placements except for the back.
For that case, if you swap the PSU and HDD spots around, you can fit a 120mm exhaust right beside the CPU area
PS, Tremeloes did a mod like that, maybe you can...
I'm using the same board and it does the same thing too. Tried with most of the settings but it still happens. If anyone knows an answer that would be great =)
if you're using the bottom slot you probably can fit a passive NB heatsink on there. any of the zalman ones are good. You can also get the thermalright hr-05, but its pretty expensive.
If you're going to use a mini ninja, it might block your first ram slots as your ram uses the tall heatsinks. I have the same setup but with an AMD 780G board and the minja blocked 2 of my ram slots.
If the ram is normal height it'll fit under the side fins of the minja.
They don't seem to be available on their website and I already tried emailing them like 5 times with no response.
As for the screws, it looks like it fits into the HDD holes but I havn't had a chance to try the CDrom holes.
