I am replacing my case (4 years old enligh), and I am thinking about
Antec SONATA
(http://www.antec-inc.com/pro_details_enclosure.php?ProdID=15138) Which
have all spects I need, but it has only 380Watt power supply. I am not
sure it is enogh.

My system is (currently+what I am getting during case upgrade):

AMD Athlon Xp 2400+
512 DDR SDRAM
nVidia nForce2-ST motherboard (Asus A7N8X Deluxe)
GeForce FX V9520 Series series card (Asus FX5200)
4 hard drives (2 SATA RAID, 1 ATA/133, 1 ATA/66)
3 optical drives (CD-ROM, CR-RW, DVD+-RW)
FireWire
3 USB devises

would 380 Watt power supply be enogh for me? I really like the fact
that Sonata is low noise.

Thanks,

Should be OK. You'll find one of the drives won't work if you're
getting close to the limit.
