The specs on the hard drive are not good. You need a SATA 6.0 HD. I'd spec a Western Digital Velociraptor. You also don't need a Terabyte of storage, unless you're going to use that blu-ray writer to download & print DVD movies. This is a work machine and Blu-ray is not necessarry for work is it? You might look into the biggest SSD you can find for the primary drive & go with a smaller, faster HD for storage if speed is really a factor for you.
The CPU & graphics card are good bets. The power supply is sortta marginal, but would probably work. Take a look at my sig. With a tower case, 650W ps, card reader & plain DVD burner, I got the parts from newegg & put it together in about an hour for just under $1400. I went with the I-5 instead of I-7 'cause I felt it was a slightly better bang for the buck. I don't do much rendering, so I didn't go with a high end graphics card w/ lotsa Vram. It's just a middle of the road card.
I'd definatly look at Xi or Alienware over Dell or HP. I'd also seriously look at a local builder / comp store. You can get what you want & not what corporate wants to sell you as a bundle. The hard drive is a big one where you don't know what you're getting, and it's the component most likely to fail, and the biggest speed clog.
