You neglected to mention that this board includes one PATA port in addition to 2 SATA ports, which covers one of Gene's wants. On the other hand, it has a single core N270 instead of a dual core D510. Have you done any benchmarking on this board? latency test? My gut feel is that it should be adequate for EMC2 but there's nothing like having some real numbers. [sidebar- Lord Kelvin wrote "I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind." Amen.] I can't find this particular board for less than apx 100USD right now, while I can get the D410MO for apx 75USD. Since I already have a power supply on hand, I don't see the need to spend more for this board. At the same time, I have a mobile-robot project in mind for my grandkids where it might be a contender. I seem to recall that even with the redesigned 945GSE chipset, comparable CPUs still consume more power than the integrated CPU solution. Looking at the Intel docs for the D945GSEJT, though, I think the higher power consumption of the 945GSE must be offset by the lower power consumption of the N270, because the power-consumption numbers look good. I have a MicroCenter store within a 15-minute drive. They offer AMD CPUs and various motherboards with a $40 discount for the combo in addition to their "guaranteed lowest price," which makes a number of AMD solutions available at the same 100USD break point. At their prices, an Intel E3300 combined with various motherboards also weighs in at about 100USD. Then there's the Jetway boards. I'm reminded of Andy's previous comment about us being spoilt by choice right now. Trouble is, the choices change faster than we can document them :-( Regards, Kent ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
