Next big update: the case itself! I didn't take many photos while actually modding as I tend to just get stuck in until it's done. It was basically a case of measuring the motherboard tray, cutting a hole in the back of the case with a Dremel and test fitting the motherboard tray. It took 5 or 6 test fits to get it right, as I had to file grooves for the rivets to allow the back of the motherboard tray to sit flush with the back of the case.
I have tapped 4 of the ventilation holes on the back of the case so that I can secure the tray to the case using 4 M3 screws.
Here's the case all gutted out ready for modding:
But first I needed to mod the motherboard tray. I cut out a hole for 2 80mm fans instead of the original single fan mount, as well as cutting a slot for the back panel clasp and a hole for the SATA cable to be hidden below the motherboard tray where the SSD will be mounted. There's also some cable management slots cut into the sides for the front panel cables as well as the 8 pin.
Once the back of the motherboard tray was cut, I used it as a stencil to cut out the back panel of the case.
Here you can see the holes cut into the floor of the case. The 2 large circles towards the front of the case are for the radiator plugs to sit in so that I can use them to drain the loop. I'll also be using 10mm extension fittings to give the radiator a little more support. There's also two holes for mounting the pump and 2 more to mount the L bracket used to hold the radiator down.
I cut out the original harddrive tray to act as a PSU holder. The fan screws will be threaded through the bracket to secure it down, and then the bracket mounted to the case. There's also a hole for the tubing to pass through to the main compartment.
This is how the motherboard will sit inside the case when it's done.
And this is where the watercooling components will sit.
Here you can see the rad is as far forward as possible which will allow room for a set of fans, but unfortunately not enough space for some shrouds as I had originally planned.
The radiator takes up a huge amount of space when the fans are installed. 130mm thickness altogether!
I had to use a 10mm extension, a 45° fitting and a 90° fitting to be able to route tubing from the pump to the radiator
They align almost perfectly.
Once everything was in place and all of the cuts and holes were made to the case, I started to sound proof it. There's two reasons for the sound proofing, firstly to try and absorb some of the noise that echoes around the solid aluminium case, and secondly for aesthetics. I didn't want a fully aluminium interior and there were a lot of holes in the case from the original Apple hardware which I wanted to cover up some how. The back panel has 2 layers of 3mm closed cell foam, the first of which has holes so that the smaller screws line up with the surface, and a second layer to cover up the small screws. The larger standoffs have been left as they will be used to support the motherboard tray and used for cable management.
The PSU in the top is such a tight fit that I had to cut out a gap in the roof sound proofing else it wouldn't fit.
And here's how it looks with the components back in. I'm thinking of adding some foam to the motherboard tray too so that it blends in with the rest of the case.
I'm awaiting a delivery of some small magnets that will be used to attach the dust filter to the front of the case, and then I think I'll be ready to install everything and start tubing her up!
