Optional items use your own dated quote. They are not checked for compatibility or treated as retailer-verified offers.

Allowance and headroom are editable planning assumptions. GPU manufacturer minimum PSU guidance is shown separately. A front radiator changes available clearance.

Save, version, share and export

Keep named builds and their versions on this browser. Download a snapshot or library backup to carry your plans elsewhere.

Technical links include component IDs, quantities, optional item names, layout and installation assumptions. Private notes are always excluded.

Build snapshots keep unknown references and custom items. Saved quote observations retain their dates; current price eligibility and compatibility checks are recalculated when loaded.

Bring your own parts list

Paste full part numbers or open a CSV. Review every selection before replacing the draft. Your list stays in this browser; no retailer or competitor pages are fetched.

Text also accepts one full MPN per line. CSV columns: product_id, manufacturer, mpn, quantity, name. Other columns, including prices, are ignored. Maximum 64KB / 40 rows. Names alone need manual mapping. Quantities count purchase units; one RAM kit is one unit.

PURCHASE COSTS
Parts, shipping and tax.
Shipping, tax, discounts and other required items
Enter combined shipping from the actual orders. Percentage tax uses known goods plus required extras after the additional discount, excluding shipping; use an amount when that assumption does not fit your quote. Rebates remain separate from immediate cash. Currencies are never silently converted.
Plan slots, cables and cooling
Your installation plan.
Some parts share lanes or need extra physical space. Choose the actual slots and record what you have checked.
Installation rules are loading. Your draft is retained if these checks are unavailable.
COMPATIBILITY
Compatibility checks.
Each result applies to the stated check. Review platform, physical fit, power assumptions and the details still unresolved.
