Not long after getting back with the box the M.2 turned up....certainly speedy and efficient delivery.
Mounted it in its bracket [doesn't use a PCIe slot and card]
Okay, if it doesn't use a PCIE slot, how does it draw power, transfer data, etc? The SSD cards I've seen are PCIE mountable, so yeah, I'm curious.
Board's in... but still waiting for the last delivery....the ram and the PSU. Can't do a lot more until they're here. Need to put the ram in...and finish cabling before the monster of a CPU fan/cooler goes in.
I found with my Thermaltake cooler, which is very similar to yours, that it's easier to fit/install with the mobo out of the case... as in you need both hands: one to hold the cooler in place, and the other to put on the nuts and tighten them. If you wait until the after the mobo is installed you'll find it's not so easy to install... so if I were you I'd take the mobo out again, place the cooler on the table/bench, then place to mobo over it, position properly and place/tighten nuts to hold in place.
That is so much easier than trying to do it the other way... believe me. True, once the cooler is in it doesn't leave alot of room to work in, but I've got big hands and managed it. Thing is to have as much of the preliminary work done beforehand... such as installing the RAM and PSU, feeding the cables through the tray before installing the cooler and replacing the mobo... again, so much easier.
It's a done deal that any macines I build from now on will have that wider recess behind the MoBo tray to hide all the wiring
My level 10 doesn't have a huge space between the mobo tray and side cover, either, but I found the trick was to feed ALL the PSU cables through the back... except maybe the one that connects to the top ATX socket if not long enough to be fed up the outside and back in. Once they're fed through you can feed them back tidily through their designated cable ports to connect to their corresponding components. Once you have done that there are tie loops to hold the cables in place. If done properly the side cover will fit without issue and your cables are hidden. Yeah, it is a time consuming, tedious job, but it can be done if you want a tidy, neat looking component compartment.
Oh and my arm is much better today... thanks for asking. 
Nah, it's all good. I have a partially fractured ulna [not broken all the way across] and some local bruising, but it's not as painful as yesterday and I've not needed any pain relief thus far. I may take something before bed, however, just to make dozing off that bit easier. Sadly, I can't look back in hindsight and rewind the tape, otherwise I'd job the bastard with a viscious left hand [thus saving myself the injuries] before taking the laptop off him. That didn't escape unscathed, either. It hit a mosaic tiled floor heavily when I was pushed off balance and through a door...now doesn't start up fully, but we're hoping the local techie can get it goung again for her.
