What I want to do is to build something that I can upgrade as I feel and over-clock to extend its performance.
Also I am trying to keep cost down on this, to justify building something that won’t be around for long. Basically right now I have a 2003 21" G5 iMac, and I am moving over to PC in order to be able to upgrade for today’s software and further down the road. So I need everything that it takes to put a system together, except Vista, I have that thanks to the university I attend.
Also as a specific question, the case I have picked out contains a power supply, or I can get the same case without the power for about $10 less, so in the interest of saving money, could I just run with the built in one and not be making a serious mistake? I tried for several hours to learn about power supplies, but I just am not getting it, a more personal explanation might help.
Any advice and help is greatly appreciated, thank you.
Unless you need RAID get a P35-DS3L. The RAM is very good but if you want to keep the price down go with some Corsair XMS RAM (2*1GB). (they had it for $25 after MIR @ newegg.). If you are willing to OC you can go by with a E21xx until you can upgrade.
You can also save ~$50 by going with an E2160 and OC'ing it. I'm planning a build right now myself and I might go that route instead of the E6550 that I was thinking about.
Everything I've seen and read shows that OC'ing an E2160 or E2180 to 3.0-3.2 GHz is easy even on stock cooling.
Not sure if you were dead set on the 4500...but the only real difference between them is the extra 1 MB cache...which I just don't think is worth it. I was looking at the E6550 which has 4 MB of cache, that's where you miiight see some difference I think. But between 1 MB and 2 MB, it's not a big deal I don't think.
