quite a confusing list of cpu spec's in the link
did a search for 89w TDP and that verified what i was told by a friend
now have a athlon 64 x2 5000+ cpu running in the esprimo.
The stock cooler seems to be coping well with it only becoming slightly warm to the touch with both cores @ 100%, top marks to fujitsu siemens for supplying such a huge cooler. Its double the size of the AMD cooler that came with the cpu.
The power supply is a little feeble, rated at 210w continuous output (well within specs for the standard sempron cpu) and has since been upgraded to a 460w one.
