Continuing this discussion I'd like to inform you that I've just received ZIF connectors:
That's how it looks in position:
It's not soldered yet. As soon as I have some time (and a better soldering iron with a finer tip) I'll post my results. I hope I won't fry my eee 
I have also received 16GB A-Data SDHC card (EEE edition)
And a 16GB Corsair Flash VoyagerGT (which I intend to solder internally)
Here are some results from HD Tune for both drives:
Enjoy!

if u get the zif connector soldered in.. there is almost no point of flash storage. With zif u can have up to 80gb single platter.. and 120gb (possibly 160gb) double platter.. that will fit if u remove the black plastic. Unless of course u are a solid state man who prefers slower, less reliable, low lifetime mlc flash.
but good work. this is a good solutions for more advance people who didnt get a zif. I made sure to get zif. My first order was on june 20th.. so it was sure to have zif, my second 901 i ordered last week.. but i made sure the mode number was one that had zif.
if i may ask, where did u find the zif connector?

Yes, where did you get the zif connector from?
How are you planning to install it?

I have posted the link to purchase them from Digikey here:

They are $5.42ea with no minimum order anymore. Their standard First Class Mail is pretty fast!

Unfortunately shipping costs from Digikey to Europe are enormous.
I bought ZIF conectors here: http://www.maritex.com.pl/pl/shop/products/ggid/9242
$1.5 each.

ah yes, I see. I wish on this international forum more people would put in a location

I am going down a similar route to this but have decided to use slower class 4 32Gb SD card for the 'file' storage like .doc, .pdfs etc (they are cheap now) and faster memory for operating system and programs. Are you planning to use the ZIF connector for all of these additions internally? I have wondered about just using SD or USB sticks direct off any internal USB connections. I think many of the solderless hub solutions used for touch screens may use a similar thing that we could take advantage of. I think I will try my corsair sticks in the 1.8" bay tonight and check for size.

I guess I'm a SSD-man
However I disagree with the assumption that SSDs are less reliable. Based on my personal experience:
- 4 of my HDDs went down (3.5" Samsung SpinPoint after 11 months, 3.5" WD after 2 years, and two 2.5" WD/Samsung - more less after 1-1.5 year)
- 0 of my 3 flashdisks (Kingston and Sandisk) and 0 of my 8 memory cards (Kingston, Transcend, A-Data, Sandisk, PQI) went down.
So to me solid state memory is far more reliable.
Yes, they are slow, a lot slower than HDDs.

I will open my eee and solder it to the mobo using a soldering iron - easy as this.
I will also solder Flash Voyager to the same points that jkkmobile used for touchscreen controller on his video.
For now I just want to check if added ZIF will work - I'm not planing to use it yet. Maybe later I'll buy a fast CF card...or an 1.8" HDD (not really like this idea).

be carefull with that +5v jkk used. It is near crucial dc-in area.. and i am not certain it can handle the same usage as a normal usb port (500mah). It can handle a low powered touch controller, but idk how much a flash drive uses?

Which +5V spot did you use for your Verizon modem mod?
Offline
i used the external usb port.. so i have no use of it now. On my last eee i played around with that +5v, i added a hub to it and put a few low powered devices, somewhere along the line i ruined my eee. I dont know if it is related.
The point is, i dont know if it is a standard+5v, and i am not going to play around with it.

So I soldered the ZIF connector.
I powered my EEE with CF-ZIF board attached and... Unfortunately LCD is off, fan is off, power and HDD leds are lit. When I connect it to power supply the battery is charging. But it doesn't work, doesn't boot and like I said the LCD is off. Any ideas?
I think I'll have to order new mainboard from Asusparts...

Packer,
Can you take some close up photos of the soldered zif connector? let's see if you made a short. Also did you try booting without cf-zif connected? did you remove the secondary ssd when adding the cf board? Did you reconnected all the wires when you put the eee back together?

Well, I checked for shorts with a maginfying glass and didn't notice any. There are no visible damages to the mobo either.
I tried booting without CF adapter, without secondary SSD...the only thing I didn't check is booting without the primary SSD.
I checked all the wires (especially the LCD one) - everything is just the same when I opened it for the first time.
When I turn my EEE on:
- Power (green one and the blue one next to the power button), battery and HDD LEDs are lit (constant light)
- the LCD is dead, it's just off
- the fan doesn't seem to work
- when I put my ear next to the machine I can hear a high pitch noise (I guess it's normal).
I can turn it off with the power button. When I connect to power supply it charges the battery.
What else can I do? Anyone knows a good way to desolder the connector? I tried desoldering pump - but it's not really a good way.

(flux-impregnated) copper braid (like this http://www.maplin.co.uk/module.aspx?Mod … mp;doy=8m8 )
Stupid question... but I have to ask.... did you replace your SODIMM correctly? (I know that EEE's do not work without ram installed)
Offline
I left the SODIMM module untouched, so it was in place all the time during mod.

Starts to look itīs.......dead.....
If every thing else fails you could send me the motherboard so I can try to repair it for you. ( I have more than 25 year experience (10 year professionally) in repairing electronics ) Most of the time these kind of things are repairable, often for very little money.
Having a working 901 myself, it will be easy measuring at various points to find the problem.

I'll buy copper braid today and try removing the ZIF connetor. If it doesn't help... Well, I have no more ideas. I guess I'll send you my mobo for revival
Offline
before hitting the zif with the copper braid and your iron.. try it out on some soldered wires to get the feeling.
Offline
packer, did you plug everything in correctly? It should work. Have you torn any ribbon cables? Are you getting any output from the external VGA port and is the HD light flashing?
I had a similar problem with my NEC Mobile pro 780 and traced it down to a torn ribbon cable!
Offline
Of a question packer, I asked my dad (an electronics engineer), did you take any ESD precautions before soldering? I know its a weird and stupid question, but it might give us an idea to what happened.
Offline
It's alive!!
I used copper braid to desolder the connector. Unfortunately I was unable to remove the ZIF completely, but I managed to remove the majority of soldering wire.
When I turned it on everything worked just fine, so I assume that there was some kind of short.
Anyways, as my EEE is working and the connector is onboard - I connected the CF board again. Unfortunately it doesn't work.
I damaged the plastic a bit while I was trying to unsolder.
It seems that connector is partly desoldered.
