I love building computers, second to that is upgrading them and behind that it's simple rebuilding them. Often I get computers in that just need a dusting out and end up taking them apart and rebuilding them with re-dun wire management just so it looks good. It may make little to no difference to performance but there is a lot of pride in artfully managing the way things fit together in the limited space of a case. Some cases let you hide wires, others you're stuck crossing them up over and around everything else, but with enough work I've found good wiring can be done in 99% of Cases. (Pun intended)
I just now had to rebuild/upgrade a system that packs Four HDD's, an Optical Drive and an SSD into the venerable Antec Cenota. I'll post Before and After here to make clear how much more thought goes into my Cable Management then most. Check out my Instagram for examples of this. I posted a Before and After of the Antec Upgrade. P67 Sabertooth, i7-2600, 16GB DDR3 RAM, Antec 500w PSU and a GT720 Graphics Card come out. Z170-A, i7-6700, 32GB DDR4 RAM, EVGA 500w PSU and 512GB Samsung 850 Pro SSD go in.
Sad that the parts coming out are still worth over $350 and still perfectly good. Sometimes Customers let us have their old parts after upgrades but here I think they'll want them back. I don't need them myself, I just did my own upgrade with the same Mobo, half the RAM and a 512GB Samsung 950 Pro NVME SSD so I'm set, but I know of many places that Sabertooth and i7-2600 could go.
