So here's the plan... I'm hoping to build this in the next few weeks, and hopefully it'll work...
Parts List

Riser Cable for Blackmagic Card - $25
Intel E5200 Dual-core Processor (http://www.newegg.com/Product/Product.aspx?Item=N82E16819116072) - $70
4GB DDR2 800 Ram (http://www.newegg.com/Product/Product.aspx?Item=N82E16820159021) - $40
Silverstone NT07 Low Profile Heatsink (http://www.newegg.com/Product/Product.aspx?Item=N82E16835220034) - $20
1TB WD Green HDD (http://www.newegg.com/Product/Product.aspx?Item=N82E16822136317) - $90
Pelican 1500 w/o Foam - $80
Dell 17" S1709W (http://accessories.us.dell.com/sna/products/Displays/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku=320-6965) - $80
12vt 12amp/hr Lead Acid/Valve Regulated Battery (http://www.batteryspec.com/cgi-bin/cart.cgi?action=link&product=66) - $30
12vt 8amp Charger (http://www.batteryspec.com/cgi-bin/cart.cgi?action=link&product=109) - $40
150Watt Car Inverter (http://www.targus.com/US/product_details.asp?sku=PA390U) - $30
These are all pretty rough estimates, but it comes in around $800
I'm looking to fit this all into a Pelican 1500 case, I've done the measurements and without foam it should fit just fine...
The 17" Dell LCD would be mounted on the lid of the Pelican case, 1440 x 900 resolution and really cheap :) It uses 34Watts maximum, but we won't need to use the screen once we're recording (Atleast I don't plan to) so hopefully it doesn't get too much usage (10-15 minutes at the most) but it still needs to exist for now.
The HDD pulls about 6 watts while read/writing... processor and motherboard should be pretty low once they're under-volted, and I don't think the card should pull much either. The lower the power usage the longer I can record.
The idea is basically so I can get full 1920 x 1080 out of my FX7 (Or any camera with HDMI) at high bit-rates with no compression for cheap... and have it fit somewhat small... Also hopefully get 5-6 hours recording out of the battery... the less power I use the better... I have about a 12 x 6 x 4" space to fit the battery, inverter and AC adapter for the computer. the current battery is 6 x 4 x 4 so it takes up almost 50% of that...
And then to actually use the system would be a little USB trackpad/buttons, only to basically launch the program, start recording, then probably unplug it and unplug the monitor.
HDMI/Composite HD/HD-SDI DIY portable capture station tutorial on Vimeo (http://www.vimeo.com/4083139)
It's like this concept, except no $800 Magma box... no $800-1000 Laptop... without the monitor it should be less than a laptop, I'm hoping 30-40 watts while recording at most.
A better solution would be a find a way to have the program launch automatically when the computer is turned on, have a very small LCD that can give basic information like HDD space left and if the program is recording or not... So I wouldn't have to use a trackpad or a bulky 17" screen.
We could probably do without the pelican and the 17" LCD... instead use a smaller LCD with a touchscreen (Which would bump the cost up about $100) and then we could store it all in a backpack... it's not very protected, but you could just pull the LCD out to make any adjustments / view what's happening (7" LCD would run at 800 x 480 vs. 1440 x 900 of the 17") and it only pulls 9watts while being used vs. 30+
But it's not very protected in a backpack for the most part, things can get bumped around and moved, so I think securing everything in a pelican makes sense. it could probably taken as a carry-on too (I think the 1500 fits in that class still) although security might look at you funny and they probably don't allow lead-acid batteries on planes...
and if I found a backpack big enough to store the pelican inside I could wear it while filming too, probably weighing close to 30lbs.. I'm filming paintball so both options work... the other idea is I could just rest the case on the ground and just run a 10ft HDMI cable out, vs. wearing it on my back... just means I'd have to be picking up a tripod and a pelican whenever I moved.
Just sorta rambling on/coming up with ideas... if anyone has any questions/ideas/input... would be cool...
From what I've been reading if you use Cineform you don't need fast HDD's or a Raid for capture, but just a faster processor... E5200 is a 45nm (lower power) but still quite fast, it can be undervolted at stock speeds to hopefully lower power consumption (but not low enough to cause instability).
I'll update as I go along, I just bought the Blackmagic for testing on my main machine, but I plan to start ordering the rest of it shortly after :) Probably going to be lots of trial and error, but it should be fun...
