Antec makes several cases with a window built in. I think the 1080 has one.
I personally run my system in a 660AMG Antec case with 330W "true power" supply. (The true power supplies can control their fan speed and the speed of 2 other case fans. A quieter system is always good.
)
I believe a 350W supply is enough Cave, especially an Antec.
My 330W Antec powers:
Asus A7N266-C (nForce 1)
2 x 256 PC 2700 DDR
Athlon XP 2400+ Overclocked to 2070 MHz cooled by Vantec Aeroflow heatsink (very nice heatsink BTW, just switched to it 2 days ago - temps 41C and quiet)
Leadtek TV tuner card
MSI GeForce 4 TI 4200 (Overclocked of course)
IBM 45 GB 75GXP drive (still going strong after 2.5 years)
Linksys NIC
DVD drive, floppy, and CD burner (Liteons)
4 Case fans in the system, 2 are speed controlled by the power supply.
