Which? Tower? Desktop? SFF? USFF?

Was ensuring heat is a non-issue also done? SFF & USFF models tend to run 
rather hot, so accumulated dust, and especially tobacco tar, within, 
especially within the power supply, can become an intermittent problem for 
"The wise are known for their understanding, and pleasant
words are persuasive." Proverbs 16:21 (New Living Translation)
