Didnt actually do too much last night, spent most of my time pondering over the standoffs. Because there is a CPU cutout in the case, I figured it would be easier to install the heatsink as I could have the motherboard upright, and have access to both sides of the mobo. Installing the backplate was fairly easy:
Hardest part of the build so far (and probably will be the hardest out of everything) was putting that damn heatsink on. After applying thermal paste on top of the CPU (I may have slightly overdone it - pea sized amount), the heatsink, due to the design of the bracket, kept slipping and sliding. Very tedious process, but it is down firmly and straight and does no longer move
I guess all I have left to do is wire up all the motherboard headers necessary, install the GPU and then I'm more or less done.
