collecting BU PC for 17K RUB

Reptoxx
17K - very little.
Here only to watch xeon with Ali, there to take a cheap 8GB memory, the same mother under the selected xeon. PSU from FSP 500-550W. The cheapest housing, cooler with dispersion of not less than 125 watts of heat. Graphics card to watch on avito, but with this budget it will be something level gtx 660-760, nothing more.
Even collecting for Ali, it is better to hold on to the 25K budget.
