I've decided on the majority of the components, although before doing the stupid thing with this amount of money, I'd rather get some personal opinions from others, if any of you have had experience with any of the parts, please let me know if it was positive or not, also I believe everything here is compatible with each other, but if anyone could do a quick check, it would be appreciated. My main problem is obviously the 1155 socket, as Intel plays their cards close to their chest, I've been trying to find out if it would support 1156 water cooling and power supplies, but to no avail, if anyone has any clue on this (with some evidence) can they please let me know. I have a fair amount to spend, after using 'hand-me-down' computers for the last 4 years, do not hesitate to mention the pricier components, although unless the 2600k comes in at a lot more than expected, I won't be looking at the extreme Intel range.
Processor : i7 2600k (to be oc'd in future, once some stable oc's start appearing)
Motherboard : Gigabyte P67 UD7
Memory : Corsair Vengeance (2x4GB) 1866MHz
Video Card(s) : (3x) HIS 2GB 6970
Hard Drive(s) : (2x) WD VelociRaptor 150GB (Raid 0) + WD Black 1TB (backup HDD) + (2x) OCZ 120GB SSD (Raid 0)
This is where my problems are though, I need a case which can fit the above in, with plenty of room for a water cooling system to go in as well.
Some I've though might do the job...
Case : Obsidian 800D / CoolerMaster ATCS 840 / ?
Then there is the problem of the power supply/cooling system, I believe I would need 1200w+ charger, I don't think I would require a 1500w one though, either way, I'm still struggling with the whole socket problem *kicks Intel*, I'm hoping the 1156 stuff can be used, just for money saving sake, as I'm sure each and every company will be trying to cash in on parts.
Sorry that its such a big wall of text, but I'd like to say thanks in advance for anyone who can give me any tips to get me going in the right direction.
