In the Assembly, no hard drives, because they already have in stock, therefore, take the more expensive mother, CPU and power supply.
In the end, the budget is exceeded 5 thousand because of the amount of memory that was originally planned to 16GB (7060,00), and the selected 32GB (13070,00).
Although the case with the PSU already there, but it was decided to take new due to the larger CPU cooler and a more powerful PSU.
Maybe something you could find better for the same money, but in General the issue was resolved quite well in my opinion.
A special thank you for the tip with the processor and its price/speed cpubenchmark.net
Update: Officially, this motherboard is not supported on windows server 2008 r2. Under it, officially there are no drivers, in particular network card.
However, in the Internet there are solutions that allow a simple "copy-paste" to modify inf and network driver is installed perfectly.
for the money, only desktop. take ASUS P8H77V-LE, the processor under it i5 or i7 processor, 4x8 operatives.
I have the "beneficiary households" as a budget platform for such purposes use the combination of AsRock Z77 Pro4-M (~$95) and Intel Xeon E3-1230V2 (~$240). Such sets of units 15-17, in months 10-12, normal flight.
Memory Hynix 8 GB DDR3 1600 MHz, 4 strap. But it was bought at $45, now about twice as expensive.
Well, reliable power is the basis of everything.
