well my old computer isn’t working anymore. i posted a thread about hopefully trying to resuscitate it but I figure I should explore the possibility of building a new one.

I used to build computers a lot in my youth, but since i got a "real" non computer hardware job, I haven’t really done much with hardware computer stuff in five years. I imagine not much has changed.

The computer will be used for audio editing/recording. So I really need a top notch sound card (which I have) and a powerful CPU. I don’t need an especially good graphics card.

I don’t follow hardware parts anymore so I just used the recommended computer parts thread to guide me and looked at the high end model.
I plan on getting all the stuff recommended below except
1. I don’t need a high end graphics card. Is there any that’s recommended for really basic computer stuff? Like I’m not a gamer at all.
2. I already have a really great case- lian li pc60. so i’d like to use that one. I am assuming that any motherboard/power supply will work with the case? Is that something I should look into more?
3. For the PSU, I would like to go modular. So I’m thinking the corsair HX 620 instead of the TX.

CPU: Intel Core 2 Duo E8400 ($120)
Motherboard: ASUS P5Q Pro ($140)
Video: SAPPHIRE 100242L Radeon HD 4850 ($160)
RAM: G.SKILL 4GB DDR2 800 ($80)
PSU: CORSAIR CMPSU-750TX 750W($100)
Optical: LITE-ON Black SATA ($24)
HDD: Western Digital Caviar SE16 WD6400AAKS 640GB ($84)
Case: Antec Nine Hundred ($120) or Thermaltake Armor Series VA8000BWS ($120)

So again all the stuff above except I’m thinking a lower end graphics card, I want to use the case I have (lian li pc60) and I want a modular power supply.

Is it safe to say that everything will go together fine?
