Hi all,
24" TFT - Dell 2408WFP
Case - This is always a personal preference issue, you need to select a case that suits the recipient of this machine
Motherboard - Big honking fan of the DFI Blood Iron Series, or the MSI P7N Diamond
CPU - 3.0GHZ wolfdale. the quads are still wasted electricity and heat at this point. (I just got a Q9300, but I am also a media phreak)
RAM - DDR2 800 mhz with 4-4-4-15 or lower latency. DDR3 is too little bang for buck right now
HDD for OS and HDD for storage (not bothered about RAID) - the previous 500gb Seagate suggestions are good
PSU - PCP&C Quad 750w: PCP&C makes the best PSU's available, accept nothing less, the 610w model would also work here, but I don't think that anyone can argue that there is no better brand than PCP&C
GFX - 8800GTX is nice, 9800GTX overheats a lot but is also nice, 9600's in SLI are amazing, cheap and they give you incredible performance. those in SLI beat any single core card (I think)
Keyboard - Logitech g15, a lot of people prefer the first edition blue one.
DVD - SATA Disc drives still have some issues with x64bit OS's
CPU - Zalman 9700, Tt Big Typhoon, Tuniq Tower. all are good
