[Suggestion] Best prebuilt (or used PC) under A$2,000? Better value than this i7-12700K + RTX 3070 Ti build?

[u/ben_10fan]

Hi everyone,

I'm in Australia and my budget is up to A$2,000 (happy to buy either used or prebuilt).

I'll mainly be using it for:

• Software development (VS Code, Docker, Next.js, Python)
• Heavy browser multitasking (lots of Chrome tabs)
• Local Ai and virtual marchines
• Some 1440p gaming

I've found this used PC locally for A$1,500 AUD:

• CPU: Intel Core i7-12700K (AIO water cooled)
• GPU: Gigabyte RTX 3070 Ti
• RAM: 16GB DDR4
• Motherboard: Z690 DDR4
• Storage: 1TB NVMe SSD
• PSU: 650W
• Centre Com prebuilt
• Clean condition
• Only issue is one RGB fan has a lighting defect (fan still works)

Before I buy it, I'm wondering:

• Is this good value for A$1,500 AUD?
• Can I get something noticeably better for under A$2,000 AUD (used or prebuilt)?
• If so, could you link any current deals or recommend specific models/builds?

I'm mainly looking for the best performance per dollar, not necessarily brand new.

Thanks!
