The official Build a PC Empire description confirms seven design areas: case, processor, graphics, memory, cooling, colours, and RGB lighting. It does not publish the complete item list, stats, prices, years, prerequisites, rarities, or compatibility rules. This index therefore begins with the verified category structure and gives you a safe way to fill the missing fields from the current game.
Verified category index
The wording “selectable design area” deliberately avoids assigning a stat that the public source does not state. A processor and graphics option probably appear meaningful to performance, but the exact relationship belongs in a dated in-game record, not an assumed hardware analogy.
Build a reliable catalog entry
For each item, copy the displayed name exactly. Record whether it belongs to desktop PCs, laptops, or both; the current company year; research prerequisites; displayed price; visible performance or appeal fields; restrictions; and the source screen. If a field is not shown, leave it blank. Do not convert the absence of a tooltip into a zero.
Add the date and current update title. Roblox experiences can change without a traditional version number, so the check date helps explain why two players see different values. If the item changes after research, going public, or another company milestone, record that state too.
How to compare two parts
Use one product as a baseline. Replace only the part under test, keep price and other components stable, and compare the displayed design preview before launch. Then develop and launch under similar company conditions. Record benchmark, review phrases, and sales separately.
A single launch is a clue, not a tier placement. Repeat when the result matters. If the year, staff, research state, or market changed, note that the comparison is not controlled. A “best” label should require a defined goal—benchmark, cash efficiency, review target, or appearance—and current supporting data.
Compatibility and balance checks
Do not invent a compatibility rule from real-world PC building. The game may simplify or abstract components. Trust an explicit in-game requirement, warning, disabled selection, or documented launch result. Record the exact message and the two items involved.
Balance is also a product question. An expensive processor may not be the best use of cash when another category is much weaker, but the public sources do not reveal how imbalance is scored. Use the PC design guide to create a controlled comparison and the benchmark guide to interpret the output.
Cosmetic choices and paid additions
The official Lighting pack description says its eight extra colours and eight animated effects are appearance only and never change a PC’s score or sales. The Decals and logos pass likewise says its marks, positions, colours, and wallpapers are cosmetic. Those statements apply to the pass additions described, and they are useful safeguards against pay-to-win claims.
Do not automatically extend that rule to every free colour, lighting choice, or future event item without checking. Instead, label the option cosmetic when the current interface or official description says so. Use visual variants to distinguish product experiments, not as an undocumented performance strategy.
Laptops and future categories
Laptops are officially described as a research unlock. When they appear, record whether the same seven categories apply, which fields change, and whether desktop parts can be reused. Do not create separate entries for rumored product types until the current game shows them.
If an update introduces a genuinely new design category, add it with its source, check date, and product scope. A renamed field should update the existing category rather than create a duplicate index entry.
Unknown fields remain unknown
The full names, exact stats, costs, availability years, research paths, rarity labels, and best combinations still need in-game testing. This page does not use a third-party list as a substitute because the audit could not establish its version or evidence chain. Players can still make good decisions by comparing the fields their current game actually displays.
