Intel S1200 Core i5 11400 2.6Ghz Six Core CPU (CM8070804497015) for $219
Note that this is the tray only version, buy a cheap tower cooler instead of the garbage the retail versions come with.
If unable to pickup, delivery was $9 to WA
Also factor in a Payment Surcharge (1%) $2.28 unless paying by Bank Transfer
Total was around $230 delivered
Note that this has the integrated graphics (unlike the "F" model)
