I bought an i5 and an Asus H87, the CPU fan wouldn't spin though. Now in the classic homebuilder dilemma of not knowing whether this is an issue with the power supply or the board; do you spend more and plow on or give up and buy a more expensive pre-built machine?
Realistically I might be prepared to spend another £60 next month to try a new PSU given the prices of gaming PCs.
However there is a point when you think a PS4 looks good for the money.
