After seeing some of the awesome builds in here it's a tad embarrassing to post mine. Anyway, here's my modified CM Scout.
I replaced the smoked side panel with one i made from a clear sheet of acrylic and fitted a 200mm CM megaflow. Top 140mm fan was replaced by a Akasa 180mm fan. Yes i did open up the top vents. Bottom 3.25" cage was removed to improve airflow from the front 140mm fan (Enermax Twister) and i made a bracket for my 1TB HDD and SSD. Watercooling is external. The two pumps (2x Aquaextreme 50z's in series), XSPC 250mm passive reservoir and it's own psu are mounted in a box. The two rads, Thermochill PA120.3, Coolgate 360mm full copper are mounted in another box on a windowsill so i get the nice cool outside air going through them. I get some stupidly low temps in the winter!!
That is a old picture and the ram has been replaced by Samsung green and the graphics card (GTX480 in the piccy) has been replaced by a GTX670 which is cooled by a XSPC Rasa universal block.
