Every PC has a paper trail.
When you order, you get a private link to a live build tracker for your PC — the same six stages every build moves through, updated as your assigned builder works on it. No jargon, no guessing where it is. Below is a demo tracker showing what the experience looks like — nothing is live right now.
What owners say about their builds.
"I've purchased gaming PCs from various companies, and this has been far and away my best experience. The post-purchase support has been unrivaled."
"The quality was on par with iBuyPower, and the experience was just as good if not better than buying through iBuyPower. Highly recommend taking a look at their options."
"One of the best experiences buying a computer I've ever had. The owner kept me updated on everything — even after the computer had shipped."
Keep your cool.
Gaming PCs that run cold under full load — so they run quieter and longer.
A small shop in Chicago.
Obsessed with thermals.
We started Bottomline Thermals in 2018 out of a stubborn love for PCs — and a frustration with how hot, loud, and short-lived the off-the-shelf ones were. So we built better ones. Then people asked to buy them.
Every build is owned by a single assigned builder, start to finish — the same person who pulls the parts is the one who tunes the thermals and signs off on ship. If they ever move on, another teammate here takes it on personally. Your PC never becomes someone's problem.
