Need help building my own system (new to this forum)

I need a new system(took a break from college and worked, now thinking of heading back to college starting august 2007). For the first time i am thinking about building it myself. I have four days where i do nothing, because of my aws overnight work schedule.
I had dell 8250, yes ancient stuff. Recently ordered dell c521 and returned it because it really din't let me put in the part from my old computer.
I will probably order the parts by end of may or early june 2007. Money is somewhat of an issue, once i get refund back from dell. $1000 is max i can spend)

Parts i already have and parts i took off from dell 8250 therfore i am not going to need

sony dvd rw/cd rw
dell dvd rom/cd rw
floppy drive
western digital hard drive 120gb
western digital hard drive external 120gb
5.1 SURROUND SOUND SPEAKERS
SAMSUNG 17INCH LCD MONITOR, ITS PRETTY GOOD SUPPORTS DVI AS WELL AS REGULAR ANALOG.
NETGEAR WIRELESS 108 ADAPTER
10/100mb ethernet/56 modem network adapter
d link WIRELESS ROUTER
logitech wireless KEYBOARD
ibm MOUSE
logitech web cam

Parts I am gonna need most likely(suggestion needed for best part that would be best for my budget and where i can get it)

unless there is a way to salvage my dell's 8250 case, a new case
motherboard
either amd or intel duo processesor
fan(quiet cooling system)
Ram
graphics card
powersupply
Any specific tools i might need to assemble (i have basic tools such as screw driver, pliers etc )
A good guide to building(have time to read up on things and am familiar with the layout of computer hardware, i work in a assembly line for mainframe servers)


Sotwares I own and will be running one of the operating system

Have xp professional sp2
have vista ultimate
microsoft office 2007 enterprise
adobe photoshop cs 10(will be using heavily for editing because photography is like a hobby)
games at the moment i own is only source(huge half life 2 cs source fan) and like gaming for most part, will be getting xbox 360 around july for free definte with games like gears of war.
grab it(freeware for usenet)
regualar internet browsing tools such as ie explorer, mozilla firefox, live messenger
Nero for burning dvd and cd

Would love to see the suggestion that would be best for my purposes. I am in US. THX AGAIN

I posted this same thing in cpu because i wasn't sure where at first..If you came across it already sorry about that.

I would say
an E6600 http://www.newegg.com/Product/Prod [...] 6819115003
a 975x motherboard http://www.newegg.com/Product/Prod [...] 6813130051
2gb of ram http://www.newegg.com/Product/Prod [...] 6820144062
a Ati x1950 Gt http://www.newegg.com/Product/Prod [...] 6814102034
and a 750w psu http://www.newegg.com/Product/Prod [...] 6817256009

the case is kind of up to you because it is a matter of personal preference this system will be upgradeable and you can overclock the processor and play most current games you could spend more on the graphics card if you wanted better, maybe an 8800 gts which are about $280

you could also get new dvd drives that are sata and it would be cheaper than getting new harddrives
