I've been making then since P2 266 days (first AGP)
Research is the key IMO.
I've been told that men are useless at reading manual, but I must be "in touch" with my feminine side cos I read them before any purchase.
I second the above....it's always nice to have another PC to jump on if you run into problems as all the answers are out there.
The most frustrating things I have ever come across (and this applies to experienced builders)
Cold boot issues. I bet some DFI users esp remember that.
Uncomputable PSUs. This happened around the time socket 939 came out, though not everyone had it. (
here TIP: if you experience problems with Antec Neopower and Truepower PSUs and also with PowerStream PSUs, try Bios 1.37 and turn the PSU off after you shut down, seems to help as well)
It has got easier though, as we don't have jumpers to mess with these days or fragile AMD cores to crush. <yes they can still be crushed.
Things that shock me...the amount of force it takes to clip down some CPU coolers, and the force required (since DDR) to fit a memory stick.
