Not for a pretty tower, but as a case maybe, then turned on its side, yuk.
What it would need is a complete cutout of the back panel, mounting the A1200 motherboard on an L-shaped tray that could have the port cutouts on the back panel, that then fit the back of the case and closed off the large gaping hole. Depending on the slot expansion used (Elbox I suppose), the slot cutouts would be also made on the new back panel of the L-shaped tray.
