I had that 60gig ssd and to be completely honest i would really recommend you go with either 2 or a 120gig ssd. The agility drives are just fine there is really no reason to pick any manufacturer over another at the moment, OCZ has the fastest most reliable drives as far as i have seen and experience. You are going to have lemons with any company, there is no perfect choice, OCZ is closer to the top rung of the ssd makers.
Step down the case to a 922. Get a 3570K if it's not too much more. Get an MSI or ASUS 670. Better coolers on those. Don't get the Agility drive. Get a 90GB Crucial or Samsung drive. Don't get a Thermaltake PSU.
