Serious Rack Mount
I cna honestly say, that I have not implemented OSX server seriously since I do not have any server class hardware from Apple to run it on. We run Compaq proliant and Dell servers here with Windows 2000 Server. All the boxes have Dual Power Supplies, Multiple Fans, Dual nics, Multi Processor, Raid 5 Ultra Wide SCSI with hot swap etc etc etc etc.....
If Apple will release a server it NEEDS this to be successful....a smaller U footprint would be nice too....Maybe 2 U....
Also it needs DDR RAM (sever Gigs worth) faster BUS, it DOES NOT need kick sound or graphics...
And on the software side they NEED better software to join Windows networks etc etc....
They also need a much security permissions....some more granular than Owner, group, everyone
.....
A box with this ....I would pay permium bucks for, our Windows server aint cheap either.....
