- Board you have chosen requires DDR3 RAM
-The SeaGate 7200.12 500GB/16MB is just as fast, if not faster than that WDC500 and costs a considerable amount less.
-The RAM is DDR2 (as I mentioned you need DDR3)
-You can find an EVGA GTS250 cheaper than the XFX version. Plus I like EVGA more for the benefits that they offer.
This is great RAM for the system you are building:
OCZ Special Ops PC3-12800 (2x2)
What size monitor do you intend on using? This will help determine how much VRAM will be necessary on your GPU. 512 or 1GB, etc..
Evga GTS 250 512MB
Evga GTS 250 1GB
I own this HDD and I love it:
SeaGate 7200.12 500GB/16MB
By the way, this is another motherboard to consider. For 5 dollars more, it seems like it has a little more to offer
Asus M4A78-E AM3 Motherboard
Personally, I would pick a case that features more benefits and airflow for the price, but it is your choice.
And that CD drive looks like it has some nice features but for a larger price than others. Check some LiteOn drives. I picked my super all-read/all-write with LS up for 30 dollars OEM on Tiger.
