If your priorities are style over substance, look in your local large computer supermarket where you could see some machines that may suit your criteria.
You may scoff at "boring beige" but the man at IBM who chose that colour was very wise. Boring beige is perhaps the best colour for disguising marks, blemishes and dust that inevitably collect on surfaces.
I was asked to buld a machine in a black case once. It was showing the grime even before it was completed - and no, it wasn't because my house is unduly dirty or dusty:-)
