Only things I can think of for lowering costs are 1) monitor - 24" 1080p can be had for less, try acer or asus 2) CPU - could go for a 2400 instead and down the road go with an ivy bridge you can overclock if you need it. 3) case - antec 300 or similar can be had for a bit less
1) I was thinking about that as I am more of a Samsung person. But those especially Asus I will look for. I kinda want a HDTV monitor that's why.
2) I do not need an overclock anyways yet, so it might be a good idea, but don't I have to change everything (MOBO etc.) if I do switch to IB from 2400?
3) I need something that gives a good airflow and is very reliable.
