Need someone to flush my desktop before summer, NOT doing it myself again $60 (Quenmire)

Last June I tried to do my own cache flush and coolant swap. I'm not going to get into what happened except to say the carpet in that room is gone now and my landlord thinks it was a cooking accident.

It was not a cooking accident.

Standard desktop, about 4 years old, running BrineOS 11. It's been on antifreeze since October and it's starting to make that sound. You know the sound. Like a wet cough but from the vents. The fluid's going thick.

I need someone who knows what they're doing to come drain it, do the flush, and swap in summer coolant. I have the coolant already, 2 bottles of ColdSnap, sealed. Yes I know ThermalTide is "better." I'm not paying $40 a bottle for computer juice.

Bring your own flush kit if you have one. I have the bucket and the hose attachment but NOT the gasket wrench. Last year's gasket wrench is in the carpet. Which is in the dumpster.

$60 cash. Should take about an hour. I'll be in the other room.
