What My DIY Desktop PC Actually Cost — Core Parts Only
I went through purchase receipts and order records to reconstruct the real cost of my desktop build (main rig: takashi-pc). This covers core internal parts only — CPU, GPU, motherboard, memory, storage, case, and PSU — leaving out peripherals like the keyboard and mouse. I confirmed the CPU/GPU against the actual running machine with lscpu/lspci, and the model numbers match the purchase receipts.
