Very nice! Thanks! The diagramme in there was very useful... useful in confirming that this isn't in fact a P180/2, but some custom-designed case Antec made for some OEM or another (probably Asus, since there was a sticker on the inside side panel explaining how to install an Asus motherboard
).
It seems to be lacking the middle fan that's supposed to go behind the upper 3.5" drive cage, although there's space for a fan to go in front of that same drive cage...
It also has a weird plastic thing that screws on top of the expansion slots and has an 80mm fan holder inside it, presumably to blow air onto the graphics card (I've removed it, at least for the time being, I'd rather use one of those Zalman brackets and fit a bigger fan on there).
It doesn't have the scifi-looking cover for the top fan, although there's a few notches up there which suggest it's supposed to have it and it's simply missing. Doesn't look as cool without it, but functionally doesn't matter. Small loss considering I got this for only £20.
The weirdest thing about it (and I don't know if it's just this or all P180/2 cases) is that there's a small plastic compartment on the side of the upper 3.5" drive cage that can be opened and closed with a little clip. There's space for maybe a few screws and a small screwdriver in there, so I assume that's what it's for, but it's still a bit of an "eh?" moment looking at it wondering why your big massive metal case has a small black plastic case inside it!
