Well...finished, took all day and into the night. Quite possibly the trickiest machine build I've ever done.
First things first, dry fit of the be quiet Silent Wings 3 fan and the ASRock mainboard. It's a tight fit for the mainboard and you really have no clearance either side:
Dry fit of the Gigabyte 1070, which on newer revisions of the Osmi simply slides in through the front:
Next up, dry fit of both on the table and determine in which orientation the Noctua NH-L12 fits. Due to the memory on one side of the board, the VRM sinks on the other side and the case fan on the top there's only one orientation where the Noctua fits. Apparently it's not the recommended placement for tower cases, but a quick internet search suggested performance wasn't really affected. Not sure why Noctua recommend not doing it but I really had little choice (apart from use a different heatsink):
With the dry fit done I had to figure out how to get the motherboard and the graphics card both into the case. After
much fiddling I can categorically declare that it is impossible to slide a 1070 in whilst the motherboard is in place. I had two options:
1. Remove the base of the case as
@Vitamin Moto did, or
2. Try and wiggle the bugger in.
I took the latter approach:
And damn near cracked the locking tab on the graphics card.
Fortunately I had
just enough space to unscrew the hex bolts holding the left vertical strut to the base of the case. After loosening that (took a
lot of force and a quality hex driver) I was barely able to get the graphics card to clear and sit where it needed to go. No harm, no foul (besides a few scuffed memory socket tabs.
If I'd loosened the vertical strut before hand this step would have been
much easier, and in fact HG just got back to me this morning (after finishing the build alas) with exactly that suggestion.
Nice and snug:
Layout of the CPU and surrounding components. You really want to plug every cable in before mounting such a large heatsink in such a tiny space. In fact if using a 2.5" SSD (I had one spare) cable and secure it to the case before you put the board and graphics card in. It's extremely difficult to get the cables routed afterwards. If you can get an M.2 drive, do and avoid that hassle.
Tada! I had to trim the locking tab on the ATX power cable to fit it into the motherboard. It's pretty tight in there:
Seriously tempted to use security screws so I'm never tempted to open this case and fiddle with it again.
