How the heck did you get it to fit???
I just got the MCW20 and realised it's a beast. The Via A64 boards seem like either capacitors or the black plastic CPU retention thingy would get in the way of mounting the block.
The nForce3 250 boads, on the other hand, all seem like the video card would get in the way.
Also, since the MCW20 has a circular bottom, the bottom is larger than the square chipset, meaning that the undersides that jut out could come in contact with low-lying mobo components close to the chipset
For examples, the
MSI K8T Neo-FSR K8T800 wouldn't work because the block would hit the capacitor. The
ASUS K8V SE Deluxe K8T800 wouldn't work also because the plastic mounting thingy gets in the way. The
MSI K8N Neo-FSR nForce 250 also wouldn't work because the block would be flush with the AGP card and there are low-lying mobo components immediately to the right of the chipset.
*sigh* Shoulda gotten a square, low profile MAZE4?
