5000 hits are not too much. Is it dynamic website? Is it php based or something else? Does it run enterprise grade stuff such as tomcat, jsp etc? Are you going to use full features of database or just store and retrieve?
If everything is basic and money is not problem:
Traditional hardware for a web server
- Intel / AMD 64 cpu with possibility to upgrade possibility to upgrade (go with entry level AMD Opteron 1212 or Intel Xeon 3050 both are SPMSs)
- 4GB ECC RAM possibility to upgrade upto 32GB RAM
- 250GB x 2 SATA software RAID 1
- CentOS / RHEL / Debian 64 bit server os
Traditional hardware for database server
- Intel / AMD 64 bit CPU with possibility to upgrade to one more CPU
- 8GB RAM possibility to upgrade upto 32GB/64GB RAM
- SAS RAID-10 73GBx 4 hard disk - 10k or 15kRPM
- CentOS / RHEL 64 bit os
If money is going to issue start degrading configurations. For high disk I/O database, I do not recommend virtualization or cloud. For a web server cloud is prefect to scale (but than again you need LBs and VIPs in front of web nodes).
In short follow KISS rule and always make sure their is room to grow in terms of RAID disk, RAM and CPU.
