I'm building a new system today in an Antec Sonata III case.
I've got this graphics card:
GIGABYTE GV-R485ZL-512H Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card http://www.newegg.com/Product/Product.a ... 6814125238
which fits in the case fine, but I've also got an Antec Tri-cool 120mm fan that I bought to mount in the somewhat unusual mid-case location that the case has.
When I tried to fit the fan in, there is about an inch of clearance between the fan and the end of the video card. The problem is that the power cord sticks out of the end of the card and bumps up against the fan.
Are there any 120mm case fans that are thinner than the Antec one? They all seem to be 25mm deep- a few are even 38mm.
