No. It uses an outdated CPU. the CPU cooler is unnecessary. The RAM is really expensive (you have to pay 90$ up front and rely on 40$ of MIRs). The HDD is slow. 7200RPM is the minimum you want for a main drive. The GPU is a workstation GPU you shouldn't use it for a gaming build. The case is mediocre. The PSU is expensive as well. This will be much better for less.
