Yes, better to buy a new case, I can recomend you an Antec Aria case. This case seems to be not very easy to install but it's looks fantastic and it's very quiet also.
BTW. I bought sblive 24. It's a low profile card but later on I realise simple fact. That is not supported (maybe works with Linux, I not sure). So I bought Sblive 5.1 (Emu10kx chipset) and this card works fine, still no support for 5.1 mode but 2.1 mode works great.
Defenitely buy a new case, it's worth to buy, you will see. You can upgrade your pegasos by adding TV card etc.
Best wishes with sblive card
