Heh, fucked up my PC then. Been messing about, swapping fan positions, taking out drive bays to keep it cool. Opened it up again before to check what ports I had available, and to move it to the other side of my desk. During this, I turned it on to see if it booted after swapping some cables, and it did. Turned it straight off.
Finished vacuuming my room, turned on the PC... "Please insert a boot drive." Bricks were shat. Loaded up BIOS, saw that my SSD wasn't being recognised. More bricks dropped. Swapped over some SATA and power cables, to make sure it wasn't those... Still wasn't being recognised (but my other 2 were, so it wasn't the cables). Thought that I may have damaged it somehow when vacuuming the dust screens on the fan because, hands up, I may have not bothered to actually take them out of the PC...
Looked online, first support topic on Crucial's website was "Why has my SSD disappeared from my PC?" Told me to leave it powered on for 20 minutes, then off for 30 seconds, as sometimes it freaks out if there's a sudden power loss. 20 minutes later, it's working fine.
I'll keep my lid closed for a while now...
Cheers. Would it be worth having 2 fans on the front (with one on the back), or one on the front, one on the side (just under my graphics card), with one on the back? Or one on the front, one on the top, one on the back? I figured it's better to have 2 in 1 out, than 1 in 2 out.
And just because I was bored, here's some pictures of inside my case. Despite having the option to put all the cables behind the motherboard (which I mostly did), you can see that cable management still isn't my strong point.
