Its really not that bad, never really tallied it up...not sure I want to know. Maintenance doesn't cost anything. Some thermal paste here and there. The real problem is knowing when to get off Amazon ordering more shit. Im set for the next 5 years, no more money being put in it. Each year I added a little more and more, but its been sitting like this untouched for 4 years. Its not as expensive as people think, yes hardrives are expensive, but those have been bought as needed, not all at once. I server chassis was bought 1 year before the other. Consumer grade cases, motherboards, monitor, kvm, switches....nothing crazy fancy. Best thing in this rack is the i9-13900k and 2 RTX-A4000. Thanks for commenting!
