I was surfing around today and i caught this review of the
Kingwin Artic Liquid Cooler that includes both cpu and gpu blocks. Its a pretty low end setup, but for $99 it seems like it size would be a perfect fit inside a sff case. It uses 1/4 tubing has 2 rads (one fits on 80mm fan mount other is in 5 1/2 drive bay main unit)
