Wes Morgan suggested this:
- Athena Power CA-SWH01BH8 Pedestal case $270
- Antec CP-850 850W PSU $109
- Samsung SATA CD/DVD Burner $20 (+ $8 shipping)
- Intel S3200SHV LGA 775 Intel 3200 m/b $200
- Intel Core2 Quad Q9400 CPU $190
- SATA cables $60
- Supermicro LSI MegaRAID 8 Port SAS RAID Controller $118
- Kingston ValueRAM 4GB (2 x 2GB) 240-Pin DDR2 SDRAM ECC $97
Total price with shipping $1100 roughly.
And like Wes says, $400 less than the Supermicro.
I also like the above with this Supermicro case:
- SUPERMICRO CSE-743T-645B Black 4U Pedestal Chassis w/ 645W Power Supply $320
- Samsung SATA CD/DVD Burner $20 (+ $8 shipping)
- Intel S3200SHV LGA 775 Intel 3200 m/b $200
- Intel Core2 Quad Q9400 CPU $190
- SATA cables $60
- Supermicro LSI MegaRAID 8 Port SAS RAID Controller $118
- Kingston ValueRAM 4GB (2 x 2GB) 240-Pin DDR2 SDRAM ECC $97
Total price with shipping, roughly $1,040. The main difference, you get a Supermicro case with a PSU.
Another interesting SATA card is the SYBA SY-PEX40008 PCI Express SATA II 4 port card for $60.
Moses/Amertrash also has this SAS3042e (pdf) which contains the LSISAS1064 chipset and can support up to four SATA devices. It is, more or less, this card from Newegg.
