On mind, it is necessary to be defined at first: whether there will be a growth over 50 persons, or is not planned?
And yes, i7, similar Xeon E3-1200v5 a series on 50 terminal users has not enough.
Will be there more than 50 or not it is not important.
As if to do that all normally it is necessary to have the equipment in a store that on a case of hit of a bomb in the server another could continue operation. Let with brakes temporarily but continued to work.
All essence in that that tasks gather the most different.
Here wrote what not , me now on 9 foreheads suffices 2 nuclear and 8 the RAM, but in . But there tasks only the server with a database.
And the task consists to leave from workstations as those. there it is necessary to one a Word, to another an ex-fur-tree, the third Internet and so on, mail reads, to the fifth it is possible still that that is required graphic editor type. it is all causes loading on a disk and on the Server. Operative storage in 128 suffices, as not simultaneously it is necessary to all.
And to put disks SAS + Spot-check. And still to space apart tasks on several disks that it turns out that it is necessary to deliver pieces of 8 winchesters.
And it will be commensurable with cost of 50 desktops with and motherboards Asrok.
Start of 50 terminals with 1 is the task powerful percents and a lot of storage, at me it is more difficult.
