Yeah, what dlfurman said...

Escept for the OCZ part. I've been using OCZ RAM for  a few years now and haven't any problems at all - zip, zilch, nada, on my own PCS and PCs I've built for others. I haven't kept count, but that's probably 50 or more OCZ RAM sticks I know of still going strong.

I've been building all my own PCs with parts mostly from Newegg since 2002 now, and I can tell you doing that will save you A LOT of money.
Plus you don't get stuck with all that OEM crap, restore disks, junkware and the like. The downside is you have no warranty, aside from the warranties on the individual parts.

For 5 grand I could build TWO monster systems that are each more powerful than the one you might buy off the rack.

But for anyone who doesn't want to learn how to assemble an optimized PC, you're far better off going to a local custom shop than, say, buying a Dell off the rack.
