Been working on the same rig since 2010, I won't even tell you the specs because they are embarrassing. The budget was 2.5K, I was attempting to essentially build one of Digital Storm's Apollo computers without having to pay the surcharge to have them do it for me.
I work primarily in Adobe After Effects (as well as the rest of the creative suite) as well as Autodesk 3DS Max and Cockos' Reaper for film composing. I'll be purchasing 32gb more of ram in the coming months and another SSD to start up a RAID configuration. Ideally, I'd like to upgrade to a server-grade mobo to house two CPUs, and hold more ram. Since completing this build I actually haven't been super happy with performance, as it doesn't seem to be a major step up from my past build, but time will tell, more on that later.
I thought this would take like an hour or two to assemble, I've been putting computers together for several years now, but boy was I thrown curve balls. For one, I've never used a liquid cooler before. Secondly, I've never used a case that utilized a PWM hub. These things combined resulted in bad times. I had hooked up the CPU cooler's fan header to CPU_FAN, and the PWM hub's main plug to the CPU_OPT on the top right of the mobo, and when I started the computer: smoke. That cord going from CPU_OPT to the PWM hub was hot as hell, and pumping out a TON of smoke. I immediately yanked out the power cord and took that cord off the mobo. I'm still not sure what caused that, but I have not tried to use that CPU_OPT port since because I'm betting it's fried. If you're purchasing the Kraken X61: be aware that the manual included AND online both suck. Do not install with the wrong screws either, it comes with 12 of them, 8 with long ends on both sides, and 4 with short on one side and long on the other: use the short/long ones to elevate the cooler head, or you'll get temps like I did initially that'll have you very worried.
Other than that, the rest of the assembly was simple. I had a lot of trouble getting it to turn on, it would just BSOD at the Windows logo, so I had to re-install Windows (and then had to do it AGAIN). The case if unbelievably beautiful. Can't say enough how much I love it, and the space/cable management is great. A lot taller than I thought it would be, got about 3 inches between the top of it and my keyboard rack, so measure your desk first!
If anyone thinks they could help me troubleshoot why it seems like I'm not getting the performance I should out of After Effects let me know, because even something like a Particular comp is still kinda sluggish. Maybe I expected too much, or I just need more ram? I don't know. Also, I'd love to OC the main parts, but I'm a little cautious about that as I've never done it before, so any advice on that would be great. I'd love to do some benchmarks and see how it performs before and after.
EDIT: Added some badass ENCOM die cut decals to the sides, I love them. Got them off eBay if anyone is curious, I'll add them to the build list.
