Celeron 600 @ 900, 1.7v, Asus CUV4X mobo.
Max temps with Seti running for at least an hour and room temp at 20C were: CPU 38C, Mobo: 32C. This with an Alpha heatsink and a Delta fan. One 80mm front intake and one 60mm rear exhaust.
I thought the mobo temp was kind of high, so I decided to try another case. About the same size but a better layout, especially space for an 80mm fan at the rear immediately behind the Alpha. (Other case had a 60mm fan lower than the Alpha.)
I cut the case so rear exhaust fan and front intake fan (also 80mm) blow straight through. Much better airflow (and also quieter).
Now the temps are (again, with Seti running for at least an hour): CPU 32C, mobo: 23C.
