*I don't need new LCD monitor+keyboard+mouse because I already have them.
All this adds up to be $542.
I'm on budget limit of $600.
1.Is there better PSU I can use than listed above or is that fine?
2. Will this setup work? 3. Is it okay for to use CD-ROM with IDE and DVD-ROM with SATA?
If you have a suggestion please tell me because this is going to be my first build
Why do you need the additional PCI network adapter? Already comes with a built-in 10/100/1000Mb network connection on the motherboard itself. Your internet connection will be well below those speeds (and thus be the bottleneck anyway).
Oh, and the PSU, that model has been recommended to me before and that's what I plan on buying for my next build.
I think you should get a SATA DVD burner rather than an IDE CD-ROM. SATA cables are less painful to manage, some games come on DVDs only, and it's good to have a way to write things for backup.
Agreed about getting a better CPU. Some X2, i.e. dual-core, would make a big difference.
Edit: check out your local BestBuy or FutureShop or WalMart or whatever you have where you live. For $600 budgets the HP/Dell/Acer/Gateway boxes they sell are typically better than what you can build yourself. Just make sure you get one with a decent video card, not integrated video.
