Upgrading my PC

[sleepsentry]

I'm planning on upgrading my Dell 4700 (specs below). I plan on ordering it tonight or tomorrow. This is my first ever upgrade and suggestions or advice are appreciated.

OCZ Modstream 520 Watt PSU:

XFX 7800GT (overclocked)

OCZ 1 GB DDR2 (adding to my current 512 MB)

Sound Blaster Audigy 2 ZS (only $64!)

Current specs:
P4 530 (3 Ghz)
512 MB DDR2
128 MB Radeon x300SE
80 GB Hard Drive
Integrated Sound

I'm also upgrading my cooling with these parts:

80mm LED Fan (to go on side of case):

120mm Fan (for the front):

PCI Slot Fan (to go below video card):

I'm looking for something to split one of my 4 pin fan connectors into 2. Any ideas of where to get it?

Does your current case support a 120mm fan size? They're pretty big. The Audigy 2 ZS is a nice price at $64, but another $80 will get you the awesome Sounblaster X-Fi video card. Even better than the older Audigy 2 chipset. If your PC already supports PCI-e, that video card is pretty darn good. I see no problem with anything else. Just double check the fan size.

Hmm, can Dell cases fit an ATX PSU? Isn't it rather small?

Yes, it will fit an ATX PSU. The Dell Dimension 4700 uses a BTX PSU connecter.
