Hi.... Was just wondering if any of you know if there is a difference between Intel CPUs which are marked BTX? Reason I'm asking is because I've seen Intel boxes that states that the CPUs are BTX whereas some don't. Looking at the CPU model #....they're the same. In case you're wondering, the cpu in question is the INTEL PENTIUM 4 630 3.0GHZ EM64T W/2MB CACHE 800MHZ LGA775-PIN RETAIL BOXED W/COOLING FAN (3 YEARS WARRANTY) BX80547PG3000F Another question - provided that the question above answer is no, there is no difference - will I be able to transplant a dell cpu (dimension 5150 - p4 630 - btx form factor) onto another atx socket 775 mobo from a different manufacturer (with a different CPU fan and Power supply)? Thanks.
