My I386 is about 200-250MB. But I integrated many other stuffs. Some large ones are: Office XP, Borland C++ Builder 4, Acrobat Reader, photoshop 6, Symantic Anti Virus, MiKTeX, LyX, several boot floppy images. And I have more than 10 small softwares on it, like Irfan. So my ISO is about 500MB. I'm planning to integrate BartPE to the ISO, it will add 150MB to the disc. I want to add a game which is 100MB. It exceeds 700MB, so I need to shrink it more. I'm testing PDF Reader which is much much smaller than Acrobat reader. I may need to decompress some files in I386 in order to make the final ISO fit to a 700MB CD
