Well my CoolerMaster Cosmos II, ASUS Maximus VII Hero mobo and CPU cooler have arrived... at long fechen last.
Oops, I did say rant off, didn't I? Still, I waited long enough... and maybe there's a little residual frustration lingering. 
Anyway, I unpacked the Cosmos II.... and what a beastie it is, too! I thought the Thermaltake Level 10 was a beastie, but this beastie beats that beastie by quite a bit. It's fechen huge! Put it this way, and not forgetting I'm not a short arse, it almost comes up to where my dangly bits leave off.... like if I were just tuppence ha'penny shorter it'd be past there and up to my hips.
According to the specs it is 13.5" wide x 27.7" high x 26.1" deep, but it sure looks and feels bigger in the flesh.
So yeah, the Cosmos II is impressive and a fine looking tower and would do any PC build proud. There is oodles of room inside - like it's massive - to accommodate even the largest of motherboards and graphics cards. It has bays for 13 HDDs, 2 are front loading and hot swappable, and space for 3 optical drives. Cable management is going to be a breeze with all the rubber grommeted cut-outs, built-in retainers and all the packed accessories, which includes PSU cable extensions, given the bottom loading PSU and just how large the case is.
Oh, and did I mention just how damned good looking this case is? No? Well it's bloody well handsome and quite elegant, to say the least... not to mention aesthetically pleasing, beautifully crafted and designed... captivating. Okay, so I'm laying it on a bit thick, but I'm so ecstatically pleased and near jumping out of my skin with anticipation over the build. Yeah, this case was proving somewhat difficult to get, and I waited some time to get it, like just on a month, but I'm so glad that I waited it out for it instead of compromising with a lesser case that was in stock. There were some nice looking alternatives available, but none compare to this beastie... not in looks, size or practicality.
Now this case was originally purchased - no, it didn't fall off the back of a truck - for a completely new build similar to Jafo's, but a health related priority came up to delay that at least 12 months, so I'm going to rebuild by current main rig in the Cosmos II and reassess in a year or so.
So, this beastie will have in it:
CPU: Intel Core i7 4790 K @ 4.0ghz.
Cooling: DeepCool 240L [twin fan] liquid cooler
Mobo: ASUS Maximus VII Hero... comes with Assassins Creed Unity.
RAM: 32gb G-Skill DDR3 RipjawsZ 2133gz.
GPU: ASUS Mars GTX760x2 4gb DDR5 x512 bit.
PSU: Silverstone 1200w Gold.
Sound: Creative Sound Blaster ZXR,
Optical: LG BluRay BH16NS40
OS Drive: Samsung 250gb M.2 SSD;
2nd SSD: 512gb Samsung Evo 250.
HDDs: 12 x Western Digital 3tb Caviar Green.
There will be a few other things, like PCIe cards for additional USB3 and SATA3 connections, etc, but that's all the main stuff for now. Yes, there's better out there, what with all the new PC tech available since I purchased this hardware, but this machine will be no slouch and it'll do me for some time to come.
Anyway, I have to go to the post office to pick up a parcel and I'll begin work on it when I get back... pics will be posted along the way.
