Lesson 1Sourcing realistic parts: verifying product listings, reading spec sheets, and cross-checking pricesBuild skills to check say online parts listings dey correct and you fit trust dem. You go cross-check specs, model numbers, and reviews from different sellers and makers, while you dey watch out for fake photos, bundles, and prices wey no straight.
Confirming model numbers and revisionsComparing specs with vendor PDFsSpotting misleading photos and bundlesUsing reviews to confirm real behaviorFlagging gray‑market or fake listingsLesson 2Interpreting current component availability and pricing from major retailers and tech sitesLearn to read real-time prices and stock from big sellers and tracking sites. You go spot trends, seasonal sales, and place differences so you fit time your buying and adjust builds to stay inside budget.
Using price history and tracking toolsComparing major retailers and regionsSpotting sales cycles and promo patternsReacting to stock shortages and delaysAdjusting builds to stay within budgetLesson 3Cooling options: stock coolers, air coolers, AIO liquid coolers, and thermal performance trade-offsCompare stock coolers, tower air coolers, and AIO liquid ones. You go weigh noise, space fit, reliability, and heat control so you pick cooling wey match your case, CPU power, and style you want.
Stock coolers: pros, cons, and limitsTower air coolers and heatpipe designAIO liquid coolers and radiator sizingClearance with RAM, GPU, and side panelsNoise, fan curves, and maintenance needsLesson 4Storage types: SATA SSD, NVMe PCIe (Gen3/Gen4/Gen5) and sizing strategiesLearn how SATA SSDs and NVMe drives differ in speed, wait time, lasting, and cost. Understand PCIe levels, size planning, and work needs so you size storage right without wasting money or making slow spots.
SATA SSD vs NVMe: latency and throughputPCIe Gen3, Gen4, Gen5 lanes and limitsRandom vs sequential workloads and QD impactEndurance ratings, TBW, and warranty termsCapacity planning for OS, apps, and dataLesson 5Case form factors, airflow, GPU clearance, drive mounting, and cable management considerationsCheck how case size and inside affect fit, air flow, and noise. You go measure GPU and cooler space, drive places, and cable paths so your builds stay cool, neat, and easy to put together or fix later.

You go compare DDR levels, timings, and ranks, and learn dual or quad channel for games, making content, and heavy memory work.
DDR generations and voltage differencesCapacity planning for common workloadsFrequency, timings, and real latencySingle vs dual rank DIMM behaviorDual and quad channel performanceLesson 7Power supply fundamentals: wattage estimation, 80+ efficiency ratings, modularity, protectionsUnderstand how to size and pick reliable PSU. You go guess system power use, read 80 Plus ratings, compare modular styles, and check protections and rails to dodge shake, noise, and future upgrade wahala.
Estimating peak and sustained wattage80 Plus efficiency levels and impactModular vs non‑modular cabling choicesProtections: OCP, OVP, SCP, OTP, OPPSelecting reputable PSU brands and linesLesson 8Motherboard chipsets, sockets, and feature sets: matching to CPU use casesLearn how to match motherboards to CPUs and work types. You go compare sockets, chipsets, VRM quality, and ports, then balance expansion, connect, and budget for games, work station, or office builds.
CPU socket and chipset compatibilityVRM design and power delivery qualityPCIe slots, M.2 slots, and lane sharingUSB, networking, and audio featuresBIOS quality, updates, and supportLesson 9How to read and compare CPU specifications: cores, threads, clocks, IPC, and TDPGain trust reading CPU spec papers and pages. You go read cores, threads, clock speeds, IPC, cache, and TDP, then link dem to games, content making, and office work to pick right processor level.
Physical cores vs logical threadsBase, boost clocks, and turbo behaviorIPC, cache sizes, and single‑thread strengthTDP, power limits, and cooling needsMatching CPU tiers to target workloadsLesson 10Building a parts list quickly: templates, compatibility checks, and saved search techniquesLearn to put complete, fit-together parts list fast. You go use templates, filters, and check tools, then save searches and alerts so you fit move quick when stock change or discount come small time.
Starting from proven build templatesUsing online compatibility checkersFiltering by budget and performanceSaving searches and price alertsVersioning and cloning parts listsLesson 11Documenting choices: writing concise justifications and noting purchase URLs and price snapshots for manager reviewBuild steady way to record part picks, prices, and sources. You go practice short, clear reasons and catch URLs, times, and other options so managers fit quick check and green light your builds.
Writing one‑sentence part justificationsRecording URLs, SKUs, and seller detailsCapturing dated price and promo evidenceTracking alternative parts and trade‑offsOrganizing build notes for manager reviewLesson 12GPU tiers and market positioning: integrated vs discrete GPUs and how to pick by workloadLearn how GPU levels fit games, creative, and office tasks. You go compare built-in and separate GPUs, VRAM sizes, power needs, and features so you pick card wey fit screen size, frames, and budget.
Integrated graphics vs discrete GPUsEntry, midrange, and high‑end GPU tiersVRAM capacity, bus width, and bandwidthPower draw, connectors, and PSU impactMatching GPU to resolution and refresh
