Then HDD fan(s), power, then dual front fan block (remember to remove the temp screws first).

Excuse shoddy photos, almost didnt take any but remembered how hard it was to find good data so took pity on everyone else.

Hoover. Good lighting.

Clear flat work surface.

Even though I have a decent workshop I found the bed to be best, good natural light and decent working height.

FF219 is just the metal case WY005 T7400 front IO panel ribbon cable HX637 T7400 front audio cable (optional if you have a proper soundcard).

Air ducting, RAM risers, heatsinks, cables, RAM, PSU, case parts most of it really.

The front panel cable and CPUs motherboard are the main differences.

T7400 and 690 versions are different although they look the same.

There are auction listings for front panels that say theyre for both but its a nomenclature fail on their part.

The ribbon cables are very similar but have different key pins.

If you felt brave you could drill out the blank one but youd have to connect to it too.

Better to buy one, got my cable for 3 inc PP, front panel for 7.50 inc PP.

The ribbon cable is not 0.1 pitch like an IDE cable, its 2mm or smaller pitch.

Stripped out all cards and drives, bent all cables etc out of the way.

Removed CPURAM air guide, heatsinks, RAM risers if fitted, RAM fan and support frame.

Removed screws holding motherboard frame in position (at rear by IO ports).

Leave Firewire cable in place where it passes under motherboard.

Beware when unplugging the ribbon cable for the IO panel, it has little teeth that hold it in and in mine they had become brittle with age or heat.

They broke even with gentle leverage with a flat bladed screwdriver.

For static reasons dont do it till all active devices are removed; drives, cards, motherboard etc.

PSU is OK.

Took me a few minutes with a decent hacksaw blade and some files to make it right.

Use a magnet in a bag to get the metal chips then hoover the case very thoroughly.

The thought of what a steel filing might do stuck in a slot or between some pins on the motherboard made me do a good job.

You will find that only the 2 side screws will fit, the centre one is offset by about 14.

I couldnt be arsed to remove everything in order to drill and tap a new hole, the IO panel is held fine with 2 screws and the power switch works so I left it.

Use a couple of screws in the front fan assemblys holes to hold the motherboard tray in position while you upend the case to screw it in place from the rear (2 screws).
