Doesn't look that good I guess?
I have more HDDs (full of important content, and I don't mean warez :S). These are not running right now as I guess my PSU is at it's limit. I have another PC which uses some of these HDDs but that's not running these days either.
1x 80GB + 2x 250GB + 1x 320GB + 1x 500GB + 1x 1TB
Only the 1TB and 160GB ones are WD. Rest are all Seagates.
My primary PC configuration:
MSI Platinum Combo, Intel Q6600 Core 2 Quad, 2GB DDR2 RAM (soon going to upgrade), MSI 7600 GTX OC, Some 600W PSU (soon upgrade), 2x BenQ 2420s, CM Stacker 830

hyeah:
Somehow I am never able to find enough time or money for my dear hardware. I went to Thailand earlier this month and saw all kinds of stuff there but couldn't find the time to buy any upgrades. Only bought a Dell 1564 Laptop.
I'm planning to spend around Rs. 20k on my PC to bring it up to date and to upgrade/service my HDDs so they all come back to shape.
Any advise for me?
Thanks again!
