Well after a lot of sweat (Thankfully no blood this time, or tears), I've gotten it operational.
It really is a monster. Currently only has 8 fans in it (Fan #9 I couldn't fit without a tiny or right-angled screwdriver, and Fan #10 requires the removal of the rack housing 4 of my hard drives) I may fit Fan #9 if I can find the means to do so.
There is an absolute fuckton of cabling in it (thankfully hidden behind the back panel in most cases, although trying to fit that back on afterwards was reminiscent of trying to squeeze everything into your suitcase when you go on holiday)
Runs remarkably quiet, except for what I think seems to be a single fan, which is a tiny bit noisy. And one fan is rotating slower than the others, so it might be slightly catching on a wire. Temperatures are pretty good across the board too, but ofc I haven't tried to do anything too extreme yet.
The graphics card is an absolute beast. The quality of its construction is immediately apparent upon getting it out of the box, and looks to have justified the price. Given that this was a bit of a blind pick going with EVGA, I have to say I'm very pleased so far. Can't wait to put it through it's paces.
Motherboard was a bit of a pain to fit, but I got there in the end. It did have a wireless chip in it, but I gave up in the end, since i suspect that was the main (or one of many) reason why the board was so hard to align with the screws. That was a bit of a shame. I prefer wired connections anyway, but unless I've got a spare ethernet cable lying around, it means I can only connect one PC to the internet until the switchover is complete (So no Playing EVE while the new PC downloads stuff and runs updates). The BIOS is a sexy beast though. Full keyboard/mouse support and a sexy UI.
Did have a bit of an issue after getting windows operational. It had decided it wanted to use one on the non-SSD (read: non - C:\) disks to create a 100MB boot partition. As if that wasn't bad enough, it meant that the remaining space was inexplicably then divided into two parts (roughly 2TB and 700GB) that could not be combined into a single drive. Hell, the 700GB part couldnt even have a drive made on it AT ALL. Eventually after some googling i found a recommendation for some software (EasyBCD) which was capable of moving this boot partition onto the C:\. So i just had to run that, transfer it to C:\, then restart the PC, go in the bios and change the Boot order to the C:\ instead of the other drive, and restart again. Hey presto, I can then format the fucker and reformat it into a single drive like the other 4.
The net result is that I now have a fully operational PC. I stopped after all that though, so I pretty much just have the clean windows install atm. Tonight I'll start installing programs, hopefully connect it to the internet to download LOTRO and install that on the SSD.
