Water cooled gaming computer built into desk

I want to build a computer that dual-boots linux ubuntu and windows 7 (already own). I will be building this setup into a desk instead of a case. I want it to be watercooled and it will be used primarily for gaming. Games such as DayZ, CSS, D3, HL2, SC2, etc. What I would like advice for is the components for the computer and water cooling system, not the desk or case. My budget is flexible because the desk will be more of a project. Please just list the best components for this situation and I would really appreciate it.

Approximate Purchase Date: e.g.: this week

Budget Range: $1000 for components + extra $$ for water cooling + $$ for desk

System Usage from Most to Least Important: (gaming, internet, video/photo editing, HDMI video playback)

Are you buying a monitor: Yes

Parts to Upgrade: I need every part. I am starting from scratch.

Do you need to buy OS: I would like to dual-boot LINUX ubuntu and Windows 7 (I already have a copy of windows 7)
