Read the rig.
The seller’s description and photos help us identify the GPU, CPU, motherboard, RAM, and storage. Those five categories make up the parts value.
HOW WE PRICE
REAL PARTS.
REAL PARTS.
REAL PRICE TAGS.
Every good flip starts with knowing what’s inside. We read the rig, match its core components to our price sheet, and show you the seller prices behind the numbers.
Match the sheet.
Our indexed prices come from real eBay listings, used-parts sellers, and new-component retailers. Each source keeps its price, condition, and original link.
Find the gap.
Add the five parts values, then subtract the PC’s asking price. A positive gap makes it a unicorn: a lead worth taking a closer look at.

Clear about what we know.
A recognized part outside our sheet gets a labeled appraisal estimate. Unidentified parts contribute $0. Cases, power supplies, cooling, peripherals, and labor are outside the five-part total.
The gap is your starting point.
Parts value minus asking price is potential gross margin. What you keep depends on achievable resale prices, condition, selling fees, shipping, travel, repairs, and your time.
A NATIONAL OPPORTUNITY.
A CALCULATION YOU CAN FOLLOW.
Our $59k daily U.S. margin potential projects the opportunity beyond the markets we’ve searched. We use listings with sellers in Texas and Washington from four posting dates: August 28–30 and September 7, 2026, valued with our current saved appraisals.

The four captured TX + WA margin totals are $8,863, $10,777, $3,149, and $4,446. Their daily average is $6,808.75. Texas and Washington together have about 39.7 million residents against 341.8 million nationally: an 8.607× multiplier. That gives $58,605, rounded to $59k.
The same sample contains 205 unicorns across those four posting dates. Scaling the daily average gives about 441 nationally, rounded to 440. The pooled average gap is $132.85, rounded to $130. Each Facebook listing ID is counted once.
This assumes other states have similar opportunity per resident. Coverage is incomplete, including a partial August 30 and a single evening capture on September 7. We have not completed a nationwide scrape or measured a typical national day. These figures describe projected gross opportunity, not verified nationwide listing counts or a guaranteed daily minimum.
