First Time Builder - Does this Look Alright?

I personally prefer getting one in addition to getting the SSD, but the problem is the extremely high price per GB once you get into the 256GB+ SSDs. Then it really isn't worth it which is why I recommend having a small SSD for your boot drive and a larger 1 - 2TB hard drive for your secondary.

If that doesn't work for your budget get the mechanical one now and then get the SSD later. You don't want to trade speed for space - that's never a good thing and 64 and 128GB SSDs by themselves will fill quickly by today's standards. Most cases now make it really easy to add and remove drives and you can always get an SSD once you get your build up and running.

As far as drives I recommend - I heavily recommend the OCZ Vertex 4, Crucial M4, Samsung 830, and Mushkin Chronos Deluxe. All of these drives are based off the excellent Marvell / NAND controllers (with the exception of the Chronos which uses Sandforce). The OCZ Vertex 4 is based on a new variant of the Marvell controller called Indilinx and it's far faster than the one used on the M4.
