Just wanted to update my Xeon posts from a number of months ago. After a false start will the incredible garbage of an ASRock motherboard (as I found to my dismay, the 1155 CPU Socket is Foxconn'e bottom quality type. After a month of use it seems the weight of a XIGMATEK Gaia SD1283 bent the pins, thus making MB unusable as well as voiding any warranty. Both Google and Newgg reviews should have been my friends- seems to occur in about 20-25% of cases).
Anyway, since the change I've had the 1240V2 set in a MSI ZH77A-G43. I went with the "H' board for the reason that the Xeon can't really be overclocked- not that I would do so anyway. I also passed on a Server board due to the fact that ECC RAM is just WAY overboard for a home system.
For those not familiar with the Xeon's, they are are very cost effective alternative to the Desktop 3770 series for a few reasons. They are just a tad slower than the 3770K stock:http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E3-1240+V2+%40+3.40GHz
but apparently do not have the heat problems that the 3770's seem to have. As mentioned above I am using the XIGMATEK Gaia SD1283 with the Nexus SP802512L-03. As I type I see the Nexus is spinning at 1050rpm and the Xeon is at 28C (system temp 23C).
Another advantage is the price. The Xeon 1240V2 can be have for about $255 at SuperBiiz.
So to sum, all those non-overclocker Silent enthusiasts should really consider the Xeon and an H board. And of course any traditional hard drives at the bottom of the case on a coolpak!!!
