Lets see how far I get with building this dual CPU rig today.

First off collect the stuff together - hopefully this is most of what I need

Image

Next I need to check that all these 2nd hand parts actually work - testing the FB-DIMMS. I added the two 120mm fans after i burnt my finger on the FB-DIMMS.

Need some help! handle of screwdriver points to central support location for mobo but there is no thread in the tray for a stud. The steel is probably too thin for me to drill and thread a hole- any ideas of how I can fix this? I feel it would be a bit risky for me to try and punch through a hole like they do in the factory.

Image

I cut down the drive bay bracket so I can fit my radiator/fans below it. I did the first cut with some new tin snips I got, then reverted back to my old faithful angle grinder because it does much cleaner cuts. The tin snips were useful for de-burring though.

Image

I have to screw in the bottom HDD bracket to get acceptable structural integrity - maybe later I'll come up with a more elegent solution.

Image

That is about as far as I got as I realised I found I was already late to take the mrs out for a meal.. oops.

do it the old-fashioned way: drill a hole and put a small nut on the other side of the steel matching with the bolt thread of the stud.

Yeah, good idea. I (eventually) came to the same conclusion. The only thing I could find that would fit was another stud.

Image

The noiseblocker fans I got come with a very nice noise isolation system which I am keen to use. However, the Black Ice radiators use larger screws, which basically appears to be non-standard and is actually pretty troublesome. So I need to do a bit of a bodge to fit the noise isolation system to the radiator.
Image

Sticky tape hole punched and applied to nuts
Image

Delicate operation of sticking the nut on. it is not easy because the threads are stamped through so there is not a flat surface to stick to.
Image

1 fan installed, 3 to go... Yes I did up the screws too tight - slackened off now.
Image

Same with the top screws for the black ice radiator - it only came with long screws so I had to go through my spares bin to find something shorter that would fit
Image

Top radiator in place
Image

This is how far I am now = the sfan power cables for the top radiator are on the wrong side because I had to put the radiator in the other way due to clearance issues...
Image

This is what the skulltrail looks like with the northbridge / southbridge heatsinks removed.

.. and not use a Dremel (I am SURE you have that) to cut the other stud to size? Shame, shame... :wink:

True, it would have only taken a moment to cut with my angle grinder 8)
I actually want to keep it for now just incase the thread on the other side comes in useful for something. I generally leave the tidying up for later (or never ;)

My next task is fabricating bodged waterblocks for the NB SB and Express doublers so hopefully I'll get some pics up for that soon.

I am also thinking ahead on how I am going to do the wiring. To reduce the faff with wiring up lots of connectors I am thinking of using some kind of screw terminals to do a lot of the joining. If anybody knows of something more elegant than 5A screw terminal blocks then please let me know. I think I also have an earth bonding block somewhere in my parts bin that I might use.

You could use barriers strips for a more "industrial" look

That is a good tip, this type of connecter is much easier to secure multiple wires to a terminal than the 'eruostyle' blocks, plus I have the option of using spade/ring connectores. I dont want PCB mounting, it is strange, molex shows this picture

Image

But I cant seem to find those on their website. Anyhow I think I am going to buy a couple of these covered 12 terminal type
