Hardware Help for Proxmox VE

Hi to all,

this is my first time posting here as a new member and a newbie in virtualization hardware configuration and hope all of you can help me.

Scenario: I want to create a cheap computer home lab where 9 virtual machines can run at the same time 24x7.
Resources Available: Old Desktop computer with the ff specs:

• Processor - Athlon II x2 240(regor)(amd-v)
• Mobo - Gigabyte m68mt-s2(can enable virtualization)
• Chipset - GeForce 7025/nForce 630a
• Ram - 6GB DRR3 (4GB DDR3+2GB DDR3) kingston (Value Ram)
• PSU - Hec Raptor 500w
• HDD - Seagate 80GB, WD 500GB, TOSHIBA 500GB (ALL SATA)

Question:

• Can my existing hardware run Proxmox VE and also can accomodate 9 virtual machines running at the same time?
• Do I need to upgrade some parts?
• Do I need to overclock?

Budget: I'm really in a tight spot with this because I'm a graduating student and has no work, so I was wondering if it can be maximized with currently what I have. But if you have any suggestion or tip I am open with it.

Thanks, your help would be much appreciated.
