First the Hardware. I bought new MB/CPU/RAM/Case/PSU/Perc 5/i HS/f to build the new server. I'm thinking I went overboard and thought maybe I should use my existing computer as my server with the new Case/PSU/Perc 5/i. Existing Desktop Consists of: 4600+ Duel Core AMD *(2.4ghz) Windsor Not overclocked ASUS M2A-VM AM2 AMD 690G Micro ATX Motherboard 2 Gigs Crucial Ballistix ddr2 800 Pc 6400 ram The problem with the board is that there is no overclocking ability for it. New Components: ASUS M3A78-CM AM2+/AM2 AMD 780V Micro ATX AMD Motherboard - Retail http://www.newegg.com/Product/Product.aspx?Item=N82E16813131330 AMD Athlon 64 X2 5000+ Brisbane 2.6GHz Socket AM2 65W Dual-Core Black Edition Processor Model ADO5000DSWOF - Retail -- http://www.newegg.com/Product/Product.aspx?Item=N82E16819103194 G-Skill DDR2 800 pc2-6400 2 gigs cl4-4-4-12 2.0-2.1v. ThermalRight Ultra-90 HS Supposedly both this CPU and ram is extremely overclockable. I've looked through reviews of the older MB and I don't see any problems with raid. Plus I'll be using the Perc 5/i so I don't really see an issue. If anyone has a thought on this I'd like to know. Second thing is what OS to use. I've said in the past threads I'll be using Windows Server 2008. I got it free through Dreamspark ( ). Seems a bit much but if there is no other real option I'm going with it. Suggestions are welcome though. My third issue is the real point of the thread. So far I have only 2 HD's that are the same make so I can't do any raid 3/5 yet. I'll be putting in 4 HD's all over 300gigs. I'm figuring that for the server's OS hard drive It would be better to have a smaller 100gig~ HD. I was wondering if this HD. http://shop4.frys.com/product/3868547 Would do with only 8mb buffer. Any and all suggestions welcome.
