Server and Array Monitoring

I’m looking for software which I can use to monitor up to about 10 windows servers (with room for expantion) which will send me information on any problems/potential problems to help me proactively monitor and support from a single location.

The key features I need to monitor are: –
1) Raid 5 array
2) CPU
3) Memory
4) Drives
5) Critical event logs
6) Back-Ups
7) Temperature
8) UPS
9) PSU

I don’t want something too detailed, I’ve found lots of examples I was just hoping someone would have something they could recommend.

Thanks
