I opened the lid by flipping two small catches and this is what I found:



In the foreground, you can see a crossmember which stiffens the case. This will be the first thing to be removed. It must be kept for future use though.

In the back, you can see the PCI slots with one card. That is easy enough to remove.

To the right of the PCI slots, you can see the processor units. There are two here and there is room for two more. They come out with the release of a few catches.

Below the crossmember, you can see the fans that cool the processor modules. These can be unclipped and removed.

In the foreground at the left, below the crossmember is the fan that cools the drive bays. That also lifts away now.

Now we come to the tricky part. The backplane, with the blue plastic cage attached must be unscrewed from the base of the case but it is not so easy. At the top of the picture, in the corner, you can just see part of the metal bracket that houses the connectors for the incoming mains power. You have to undo the mounting screw and then jiggle it about inwards and then upwards to get it to come clear. One of the mounting screws for the backplane is hidden beneath this so you have to get it out.

Once you have done that, the back half of the case is empty.

(More to follow)

BinaryLimited:
jpoc: OK, here are the first few photos.

This one shows the unit as received from trademe. It is a Sun v440 server unit. As mentioned above, it cost me $10.

Now looking at the internals of the front part of the case.



You can see the screws that need to be released to allow you to remove all of those fans. There is no need to remove all the small PCBS but pulling the cables out will make your life easier.

Halfway up, on the left, just behind the red, white and black cable assembly, you can see a small metal flange. That is part of the hard disk cage and it is bent round and spot welded to the side of the case. You are going to have to deal with that later.

Next we have to pull the PSUs.



Now is a good time to remove the rack mount lugs and the front doors. They just unscrew and you probably want to keep these for later.

The PSU fastenings are labelled on the front. You just undo those and pull the units out.

The PSU cages are pop-riveted onto the front panel. You will have to drill the pop rivets out from the front. It is easy enough. If you use a small drill bit, you will most likely just make the rivets spin round, use a larger drill bit and all is good as. Once you have removed the rivets the cages should just unslot from the base. It might be easier if you remove the dvd drive first.

Here you can see the drive cage.



As with the PSU cages, this item is pop riveted to the front panel. Drill them out.

Then you hit the worst part of the stripping process. The drive cage has a small flange at the rear. (Remember the earlier photo?)

As I mentioned this flange is spot welded to the side of the case.

I do not propose to start drilling out spot welds. It is a thankless task as the weld metal is often very hard.

So, I just sawed through the flange as close to the side of the case as I could.

I used a multi-tool with a saw blade attachment. It made decent progress through the flange without blunting the blade.

Then I just had to remove a few odds and ends from the case, door clips and the on off switch and we were good to go with a stripped case.

Next I will post photos of the bare case and start on cutting away the front and rear panels but that will be after the weekend.

I am still working on the design for the drive mounts but my top candidate will be able to take 24 3.5" drives all tool free hot swap!

Have you guys seen BackBlaze's storage pod design? They open sourced the design from the beginning so you could potentially get them made locally.

Yeah, I've been following that blog for a while. I never really considered the idea of having the case made locally, because I felt like it'd be a small (or single) run, and that would push the per-unit costs up pretty high. (It is tempting to try and fabricate it myself though!)

Plus I found it quite hard to locate the backpanes they use?

Nice, they are pushing the limits of off-the-shelf stuff. 

I like this kind of project.
