Looking for advice here, as I know next to zero about hardware. I have a 6-year old trading computer, and was about to replace it when I began wondering it would be possible to renovate. Meaning, replacing motherboard, fans, etc. I replaced my hard drive recently, and run 3 monitors off the system, so it seems it might be less of a hassle to renovate and upgrade, if that is possible. With a completely new system, of course, I'd need to reconfigure and reload everything. Not fun. The components of my present computer are in a large case, easily accessible. This isn't something I'd do myself, but turn over to a shop. Opinions appreciated.
