Still a few months away but one thing that could trip me is the power requirement to run 8 computers at once.

I'm planning on Sandybridge CPUs, probably with H67 mobo as I'm not planning to overclock and H67 would have onboard video, which would save me about a grand from not buying 8x video cards.

8x H67 (or Z67 if they come out and are decent), 8x 2500 (not K), 8x HDDs, using USB drive to install Linux. I get the impression at most 300w would be needed each, would that be about right?

That would mean about 22 amps total :shock: my current house wiring won't be able to handle that unless I unplugged everything else, and with solid wood walls all around, running a new 110v line is not an option. Wiring in my house is about 50 or so years and multiple rooms are wired to single breaker. 3 computers and everything in my room is half of the total 20A max, leaving a scant 10A left for other bedrooms, living room, and bathroom. If someone used a hair dryer while I have all 3 computers on, the breaker blows.

However there are unused 220v line that I can tap into, and 220v feeding 8 computers would reduce current to about 11A (amp x volts = watts) and defiantly doable. Most PSU has either manual 110/220v switch or auto switching and should be covered.

Am I right so far?

Ok, next: computer power cord for the PSU in USA are generally for 110v outlet. The 220v outlet in USA aren't normally used for computers so finding power plug for USA 220v ro computer PSU would be real hard. Would I be better off if I tried some European style plug as computer power cord exists with European plug? I can see loads of them plus power strips with European plug on various online sources cheap enough.

Alternately I can defy the USA standard, use standard 110v outlet wired to 220v circuit but have them painted in like red (with red plate) and put label warning it is 220v not 110v? If the inspector decided on a surprise visit, he'd probably have a heart attack, then have me drawn and quartered for this practice. :chair:
 
well your 220 line is just two 110 lines and a neutral just split the lines and use two receptacles,or go to the generator section at homedepot and buy a 220 to 110 splitter. i personally hate to run anything on 220 unless absolutely necessary like a welder,but never my pc=))~ you didn't mention if you have a 3 or 4 prong 220 outlet so here is a general search for the splitter youll have to find one with the plug you have or you could always switch the plug to one that matches the cord you like http://www.google.com/search?q=gene...tle&resnum=3&ved=0CDgQrQQwAg&biw=1842&bih=821

If you want help putting them together and setting them up let me know. I love tinkering and I shouldn't be too far from you(Toledo)

I have cat5e cables as well, or can make custom length cables.

Obviously if you're not getting the K model then you can't overclock. I can't find out if the 2500k will complete the deadline for -bigadv at stock clock or not. Aslo if they are capable of bigadv's you won't find it in Linux anymore. Windows is rocking the bigadv now. Find yourself some 80gb sata's and rock out with your farm out. Maybe install w7 to usb and run off usb instead of having hd's everywhere.

3 lines, I see red, white, and black. No bare or green. When I checked the power I got 220v between red and white and 110v between red and black, and 110v between black and white. When I checked between red and a nearby copper pipe, I got 220v, 110v from black to pipe, and just a few volts from white to pipe. The basement used to hold variety of wood shop tools including a bandsaw, lathe, etc but it was all gone (given to my aunts and uncle) when my Grandpa passed away almost 30 years ago.

It's about 2.5 hours drive if you're wondering. But if I can stay at my Brother's for a few days he lives south of Ann Arbor.

I'll keep you in mind... if I remember. I'll probably need it as I'm going to find 8 port hub with 1 upstream port so I'd probably like custom length cables to keep it neat.

H67 doesn't support overclocking. Putting a K series CPU in H67 board is probably like using Porsche engine without transmission. Stock CPU cooler can only handle so much heat and I'm not going to bother getting 8x fancy low profile coolers or massive WC rig.

Ok :D Any place up there the wife could shop while we are working? :D. I didn't pay attention to the H in the 67 :D If you went with P's you could run the CM 212 which would do a good job for oc'n and they are only $20 only need 1 more fan per cooler.

Let me know when you are ready to do it or ready for the cables. I'll have to steal my tools back from my buddy.
