I noticed you have specified the x-fi, without the speakers its an extra £10 for the creative set, would be cheaper and better than the 2.1 speakers you have got on your list! also dont bother with the raptor, get two SATA disks and RAID1 them, thats just my opinion though, its faster cheaper more storage.
edit: also consider the antec p180 i have just taken delivery with a scythe ninja and they are excellent, build quality is superb
