Live counts and real prices, so a band only appears while there is stock behind it.Build a custom PC — Free online custom PC builder: set a budget and get a complete compatible machine, or pick every part yourself — CPU, motherboard, RAM, GPU, storage, PSU, cabinet, cooler and monitor. Socket, memory, power draw and physical fit inside the cabinet are checked live. Ask whether your configuration runs a named game or program — GTA V, BGMI, Valorant, Cyberpunk 2077, Premiere Pro, Blender, AutoCAD, Tally — and the answer is worked out from the parts you chose rather than guessed. Every PC is assembled, cable-managed, BIOS-updated and stress-tested before delivery.Computer & laptop repair — Computer and laptop repair in Mumbai — diagnostics, screen and keyboard replacement, RAM and SSD upgrades, virus removal, data recovery and annual maintenance contracts.Refurbished laptops — Tested refurbished and second-hand laptops in Mumbai, with the grade, condition and warranty stated for each machine.Business & bulk supply — IT procurement for businesses — bulk and dealer tier pricing, GST invoicing, quotations and fulfilment for offices, institutions and resellers.Wholesale & trade supply — Trade supply of computer components in quantity to resellers, system integrators and repair businesses in Mumbai — send a parts list or part numbers, get an itemised and dated GST quotation, and see verified tier pricing applied automatically across the catalogue. Order minimums, payment terms and delivery timings are agreed per account rather than published as one rule.Custom gaming PC builds — Custom gaming, creator, CAD and local-AI PCs built and tested in Mumbai. Explains how the workload decides the parts, what compatibility is checked before anything is bought (socket and chipset, memory generation, GPU clearance, PSU capacity and connectors, cooler height, M.2 keying), and what assembled, BIOS-updated and stress-tested actually means here. Each component keeps its own serial-numbered warranty on the invoice.Workstation PCs — Custom workstation PCs configured and supplied in Mumbai for CAD and engineering (SolidWorks, Inventor, AutoCAD, Revit), 3D rendering (Blender, 3ds Max, Maya, V-Ray), AI and data science, software development, and video and colour work.

Carries a live price ladder of complete machines built from current stock, a count of the server platforms that can actually be completed today, and a desktop-versus-tower-server-versus-NAS comparison that will recommend a NAS where a NAS is the better answer.

Support & Guide Centre — Practical support guides written by the counter and workshop team — desktop and laptop upgrades, compatibility checks before buying, troubleshooting trees for no-power, no-display, undetected drives and overheating, Windows and driver problems, plus orders, invoices, delivery, returns and warranty. Each guide states who it applies to, its safety level, and the point at which to stop and ask a technician.Component news & comparisons — What is actually new on the shelves, written up from the published specifications rather than from a press release: processors, graphics cards, memory and storage, what each figure commits you to in the rest of the build, and side-by-side comparisons of the parts people are choosing between. Prices and stock are the shop’s own, in Mumbai.Machines we have built — Custom PCs built and tested in the Mumbai workshop, filmed with the full parts list and the reasoning behind each choice. Every showcase resolves its parts against the live catalogue, so it shows what the same machine costs today and which parts have changed or been discontinued since filming.Lamington Road buying guide — Independent checklist for buying computer parts at the Lamington Road market in Mumbai: how to compare two quotes like for like (SKU revision, GST inclusion, payment surcharge, warranty type, quote date), how to verify a part is what it claims to be from seal and serial number, the compatibility mistakes that come back most often, and when to stop and ask a technician. Written to be useful whichever shop you buy from.Track a repair — Check the live status of a repair or service job by ticket number.Build guides
