Here's my setup.
Cooler Master Stacker S1000
ASUS Maximus Formula motherboard
Intel Core 2 Quad Q6600 cooled by a Cool-It Systems Freezone Elite
4 x 2GB Mushkin PC2-6400 DDR2 memory (8GB total)
1 x Seagate 1TB Barracuda 7200.11 SATA HDD
4 x 500GB Maxtor Maxline PRO 7200rpm SATA HDDs
1 x LG DVD-RW drive
ATI Radeon HD3870X2 video card
Dell 2408WFP 24" LCD
Logitech G15 keyboard
Logitech MX Revolution Mouse
Logitech X-540 5.1 speakers
Medusa Speedlink 5.1 headphones (v2)
As for that Freezone Elite cooler, it's a TEC-based self-contained water cooling setup. At stock speeds, my CPU is running around 18 degrees Celcius idle, and 25 degrees under load. I'd overclock, but until I fix the horrible Northbridge heatsink on this motherboard, I won't be able to go very far.
