For some who dont know, there will be a new type of case coming out, It's Called BTX.
Balanced Technology Extended.
Currently we have the ATX case, which is called Advanced Technology Extended.
Here's a website with pictures. I know its not in english, but if you just look at the pictures, you can understand it.
For myself, im not looking forward to the BTX cases because i believe the motherboards might be built differnetly and the PSU is already built differently, so once again! dont go out wastin money on a expensive PSU!
