So, someone on craigslist locally posted that they were selling their dual-core 4 monitor day trading computer because they were planning on upgrading to a quad-core 8 monitor setup (somewhat rediculous if you ask me, but thats what he "needs"). The link they posted for where the old computer was purchased was quite overpriced so I saw an opportunity to make some money by offering to build him one myself. I just sent him an email so I don't even know if he already bought one or not yet... So, below are my initial ideas on components... Qty:1 - Lian Li PC-A59B Case - $89.99 Qty:1 - Gigabyte GA-EP35-DS4 - $169.99 Qty:2 - PNY Quadro4 NVS440 256MB 128-bit GDDR3 PCI-Ex1 - $409.99 Qty:1 - Highpoint RocketRAID 2310 PCI-Ex4 - $119.99 Qty:1 - PC Power & Cooling S75QB 750Watt PSU - $149.99 Qty:1 - Intel Q6600 - $249.99 Qty:2 - Corsair XMS2 2x1GB DDR2-800MHz 4-4-4-12 - $69.00 Qty:3 - Seagate 7200.11 500GB - $109.00 Qty:8 - Samsung 2253BW 22" Widescreen LCD - $289.99 Qty:2 - Sony NEC Optiarc 20x DVD Burner with Lightscribe SATA - $27.99 Qty:1 - Arctic Cooling MX-2 Thermal Compound - $6.99 Total: $4,450.79 with monitors Total: $2,130.87 without monitors OS: Don't know yet whether he wants Vista or XP. This was my intial thoughts/offer and is likely to change some. I already think I will add a 250GB or 320GB drive for OS/progs that will be separate from the RAID to prevent accidental data destruction in case of reformatting. Thoughts/opinions?
