Building a new PC

So I'm contemplating building a new PC from scratch, preferably for gaming/HD video. Already have a new 575W 20+4-pin Dual-Fan ATX Power Supply coming (http://www.geeks.com/details.asp?InvtId=PS575X2), ASUS P5G41-M LX2/GB Intel G41 Socket 775 mATX Motherboard (http://www.geeks.com/details.asp?invtid=P5G41-M-LX2-GB-BO-R&cpc=SCH) and XFX Radeon HD4650 1GB DDR2 video card (http://www.jr.com/xfx/pe/XFX_HD465XZNF2/). Am planning to use existing SATA hard drive, disc drives and RAM, what else would I need?

 

Oops scratch that power supply I mentioned, I found this case that comes with one: http://www.geeks.com/details.asp?InvtId=CS51WBK

So it will be that case and power supply, an ASUS P5G41-M LX2/GB Intel G41 Socket 775 mATX Motherboard http://www.geeks.com/details.asp?inv...B-BO-R&cpc=SCH and a XFX Radeon HD4650 1GB DDR2 video card http://www.jr.com/xfx/pe/XFX_HD465XZNF2/

I realize that I will also need a processor, been looking at http://www.geeks.com/details.asp?invtid=BX80557E6420SLA4T&cat=CPU that one.

I've checked and the motherboard, case, power supply and processor / processor fan say they will work with each other, is that the case?:confused

 

Umm, a PSU that comes with a case usually sucks and this is the issue here. The rest is fine.

 

The case i got has a built in Power Supply and 1 fan, it didnt come with a CPU. I'm looking at http://www.geeks.com/details.asp?invtid=BX80571E5500-DT&cpc=SCH and then a fan for it.

 

lol sorry im retarded. i got PSU and CPU mixed up. Yes the case comes with a PSU, however I have already ordered a different one: http://www.geeks.com/details.asp?InvtId=PS575X2

That look better then the one that comes with my case?
