Jimbos would work well I would agree.
DFI also makes nice mobos like this one http://www.newegg.com/Product/Produc...82E16813136152
I might recommend a good PSU (Power Supply Unit) for your new system. Sometimes people tend to skimp on their PSUs. I would maybe stay away from the "Generic" "no name brand" (hehe) types of PSUs.
Antec, Sparkles, PPC, are good PSUs. I'm sure other people could add more to the list of companies that make good PSUs. I would maybe recommend a PSU that is above 400W in power.
I would also recommend some Arctic Silver 5 (AS5), which is thermal paste that goes in between the CPU and its heatsink/fan. AS5 will transfer the heat from your CPU to the heatsink better than the thermal paste that the CPU comes with. AS5 should reduce your CPU temperature by a few degrees which is worth the $10 you spend on the tube of AS5.
It took me a few days to build my first computer. I "tried" to be very careful and read most of the instuctions. I had to tinker around with the machine a bit before I got it to run stably.
