19" Samsung 997DF monitor ($200 at BestBuy - $20 rebate)
You'll need to check these prices from [link|http://www.newegg.com|http://www.newegg.com] :
Motherboard: Asus A8V Deluxe (VIA K8T800Pro chipset), Socket 939. Uses non-ECC, unbuffered DDR400 RAM (4 GB max). Promise 20378 RAID. $129.00
Processor: AMD Athon64 3400+ (2.2 GHz), Winchester core (0.09 um). OEM. $269.
Memory: 2 each 512 MB PC3200 RAM (~ $85 - $115 each). Check for Asus Qualified memory, but most name-brand stuff should be OK. Get PC3200 memory so the processor isn't waiting for data any longer than it must.
Hard Drives: 2 each Hitachi 160 GB 7200 rpm/8 MB/Ultra ATA 100. 3 year warranty. OEM. $93.00 each. Setup as Raid 1 (mirrored). If you have a good backup strategy, you can run these in Raid 0 for better performance.
Rosewill Radeon 9600 128 MB, 128-bit video: Retail $78.00
Antec SX1040BII (400W) case: $94.99.
Plextor EIDE 12x DVD+/- RW drive. Retail. $105. (The SATA ports on the motherboard won't work with the SATA version of this drive so get the EIDE version.)
There'd probably be another $75 in case fans, CPU heat sink and fan, and misc. parts.
Something like that should be reasonable. You'd have some money left over for a keyboard, mouse, multifunction card reader, wireless networking, software, etc., as needed.
Or you could simply get a Compaq SA4000Z with XPHome and similar specs for $1374 after $50 rebate (with no monitor). [link|http://www.hpshopping.com|http://www.hpshopping.com]
