Whats the smallest HTPC case I can get for ATX motherboard?

[Spooter]

Hi all,

Got a spare AMD X2 6000 now and 8200 motherboad so it makes sense to build a server/htpc.

The only think is I dont want anything to big and £100 or less?

Silverstone has a few - but size wise they are just narrow midi tower on their side.
GMC make a few if budget features are acceptable.
LL V600 / V800 (if you can find one)
The LL A05 / PC-50 is also a nice little atx case - but not destop style
