[Solved] Case opinions?

Approximate Purchase Date: opportunistic, grabbing parts as good deals are perceived - before xmas 2010.

Budget Range: Under $1000 TTL, etc.

System Usage from Most to Least Important: general home PC, web, docs, home photo, some games (preschool), view videos, music, accounting, *maybe some work - web application development*

Parts Not Required: keyboard, mouse, monitor, DVD/CD burner

Preferred Website(s) for Parts: newegg is good enough to get an idea

Country of Origin: US

Parts Preferences: name brand, quality parts preferred

Overclocking: Not necessary

SLI or Crossfire: Not necessary

Monitor Resolution: 1920x1080 (minimum desired) (2 monitors eventually)

Additional Comments: a quiet PC is always good, a case with room to upgrade. Idea is to buy at the bottom with core components that can handle today's best. When today's best is a bargain in 3 years - upgrade the processor/video card/power supply/RAM/etc as needed.

OS - Not much to change with this one.

Motherboard - Thought here is that it has USB3.0 and can handle plenty of RAM,will accept a top notch video card, will accept todays high and low end AMD processors.

Processor - a good processor for a good price

SSD HD - because changing the system HD is such a pain, it's worth it to me to get the SSD that I know I want now at build time...or it just might never happen.

RAM - Contemplating just 2GB here, but I know that going from 2 to 4 for $40 is worth it - so rather than debate it - I'll just do it and prevent myself from being able to complain about it later.

VideoCard - just a simple video card that will handle basic tasks easily and allow me to plug in 2 monitors.

Case - and power supply - this is where I don't really have much of an opinion. I want a case that provides plenty of room for my fat fingers to build this PC. I have a Fry's about 5 min away - so I'll be able to get whatever extra cables I might need. I'm not sold on this combo, I'd be willing to get just a case and locate a premium power supply...but I don't really know what that means.

What I'd like help with is the Case and Power Supply.

Power supply option 1 would be a quality supply that is slightly over powered for the above system as-is (as opposed to slightly underpowered).
Power supply option 2 would be a quality supply that is oversized to accommodate the growth potential in processor and video card.

For the case, I'm more interested in it's general convenience - ease of build - convenience of ports (front USB, etc) - anything to consider with USB 3?

Thanks in advance for any comments!
