The just released 45nm AMD parts[0] are intended for Socket F (formerly occupied by Opteron parts) - which is part of the 2nd (more expensive) server (pricing) tier. And these parts are priced accordingly. In a few months, AMD will release the workstation (lower priced tier) version of the current Shanghai (aka Phenom II) part - and it's likely that this part will be absolutely killed by the equivalent version of the Nahelem (aka Core i7) parts that will be available at the same time. Actually the Core i7 parts will probably be widely available before the AMD equivalent parts. :( So #1: I said "now" (today)[1] and #2 the motherboards and CPUs I mentioned will allow the OP to build a system where the overall performance will be limited by the system disk drives and installed memory. Building a system with more internal memory to CPU bandwidth, or some other exotic system feature, will not change that. Another point worth mentioning is that its far better, and economical, to build a home NAS based on proven, mature, widely available commodity parts rather than trying to build it based on brand new, rev ~ 1.0 BIOS based products that have not even been reviewed by the usual tech review sites.[2] [0] http://it.anandtech.com/IT/showdoc.aspx?i=3456 [1] Neither Core i7 parts or AMD 45nm Shanghai parts are listed on newegg.com. [2] nothing on tomshardware.com or many other review sites in terms of detailed performance level evaluations of the AMD Shanghai parts.
