Lian Li are tooless also. They use thumbscrews on freakin EVERTHING.
Anywho, A new HSF would be a good idea, but isnt crucial. 65 is where you need to worry, but like I said, I would go ahead and do it.
As for components, that Vantec is a nice HSF choice, especially on a budget. Cant beat $25 for a quality HSF. Personally I HATE Tt cases, but merely because theyre far too flashy for my taste. Tomorrow Im placing a $2100.00 newegg order, and a Lian Li is on the list.
However, Tt does make a decent case, AND they have like 7 damn fans in em. So cooling will improve, but they tend to be quite loud.
System specs? Lets just get down to it people:
