here are a couple things you may wish to consider...
1. your motherboard is a Crossfire board but you are purchasing a Nvidia card. this is fine, however, you will not be able to use another nvidia card and go SLI.
2. i recommend not purchasing such a ridiculously high priced harddrive. i faster harddrive will NOT make your computer faster, it will only make reading and writing off the harddrive faster. if you plan on using this computer for gaming, it will only make the game load faster, not play smoother. however, if you have the money and dont care that its only 73gb, then go for it.
3. as for the blue ray burner, i cannot see why you really need it, but again, if you have the money then go for it.
4. if your spending money on $170 harddrives and $260 blu ray burners, why not get a better video card? i suggest a 9800GTX, or if you really have money to spend, a 9800GX2.
5. i suggest a power supply manufactured by corsair or OCZ, they both sell good quality power supplies. also i would suggest around a 750w because 1000w is a little excessive.
