Frequently Asked Questions (FAQ)

As long as your order has not yet been processed or shipped, we will try to make changes or a cancellation possible. This can include, for example, the delivery address, quantity, billing details, or individual items.

Please write to us as early as possible with your order number and your request. Once the order has been shipped, we generally can no longer change it. For consumers, the information on the statutory right of withdrawal under Returns applies after that.

Yes. Add all desired items to your cart and complete the order together. If you have already placed several separate orders, please contact us as soon as possible with the order numbers. We will then check whether combined shipping is still possible.

Please note: For particularly large, heavy, or items with different availability, it may be advisable or necessary to split the delivery.

We keep our stock levels carefully up to date. If an item is still unavailable after you place your order, we will contact you promptly. You can then decide whether you would like to wait for it to become available again, choose a suitable alternative, or cancel the item.

We will never replace an item with a different model without your consent.

Yes. Lunium supplies private customers, freelancers, and businesses. If you need larger quantities, have regular requirements, have special needs, or require a custom selection, please contact us before placing your order. This allows us to properly coordinate availability, technical requirements, delivery times, and potential alternatives.

For larger quantities, custom systems, or special requirements, please contact us in advance. Briefly describe what you need, the planned quantity, and when the hardware is required. We will review the options and get back to you with a suitable proposal or any follow-up questions.

The available payment methods will be displayed to you at checkout. Depending on your order and the country you have selected, different options may be available, such as PayPal, credit or debit card, Apple Pay, Google Pay, instant payment, or other payment methods offered through Shopify.

Please rely on the payment methods that are actually displayed to you at checkout. These are available for your order and can be used securely.

If payment by invoice is displayed at checkout, you can select this payment method directly. For larger orders, recurring needs, or custom projects, businesses can also contact us before placing an order. We will then check whether and how a suitable arrangement can be made.

Please note: Payment by invoice is not automatically available. Availability may depend on the order value, payment provider, company details, and an individual agreement.

Depending on the payment method, you will receive the invoice by email, in your customer account, or with your order. If you cannot find the invoice, please also check your spam folder.

If you need a copy of the invoice or if the invoice details need to be corrected, please contact us with your order number. We will assist you promptly, provided that the change is legally and accounting-wise possible.

As long as the order has not yet been finalized or the invoice has not yet been issued, we are happy to check whether an amendment is possible. Please contact us as soon as possible with your order number and the complete, correct billing details.

Once an invoice has been issued, amendments are only limited. In this case, we will check whether a correction or cancellation invoice is required and possible.

Yes. The payment is processed through the checkout and the payment providers integrated there. Lunium does not store complete credit card or payment data on its own systems.

Please make sure that you only make payments through the official checkout of luniumsystems.de . We will not ask you via email or messenger to share payment details or passwords. Familiar payment methods and a clear checkout reduce uncertainty when shopping online.

Yes. Briefly describe what you intend to use the hardware for, your requirements, and your approximate budget. For existing systems, providing the manufacturer, exact model numbers, installed components, or photos is also helpful.

We do not advise based on the principle that "more expensive is better." Our goal is to find a solution that suits your intended use, offers sufficient performance, and makes sensible use of your budget—whether for a single PC, a workstation, a server, an upgrade, or a network project.

Yes, provided we have the necessary information. It is best to send us the exact model number of your system, the model number of the existing component, and the item you wish to purchase. The more precise the information, the more reliably we can assess compatibility, limitations, and possible alternatives.

With servers and enterprise hardware, compatibility can depend on, among other things, the platform generation, CPU, RAM type, firmware, controller, backplane, PCIe slots, power supply, and manufacturer approvals. That is why we do not simply check whether a part generally looks similar or has the same connector.

Yes. We support custom workstations, servers, upgrades, and network solutions. Let us know what the system needs to do, which applications or workloads are planned, whether existing hardware should be integrated, and what budget is available.

For businesses, information on the number of users, virtualization, storage, networking, redundancy, growth, and the desired implementation timeframe is also helpful. Together, we will develop a technically sound, well-justified configuration—without unnecessary components.

Yes. You don’t need to know technical jargon to make a good decision. Simply describe what you need the device or component for—for example, gaming, working from home, photo editing, video editing, programming, running a home server, or data backup.

We explain the differences in plain language and tell you clearly which features make sense and what you probably don’t need. That way, you won’t pay for performance that offers no real benefit in your everyday use.

Yes. If you have any questions after purchase about the delivered hardware, installation, setup, or use, you can contact us. We will assist with technical questions to the best of our ability and work with you to find a solution to the problem.

In complex server, network, or software environments, full remote support or a guarantee for the entire environment may not always be possible. Nevertheless, we will not leave you without answers to straightforward questions and will clearly explain what information or next steps make sense.

We process orders as quickly as possible. The exact processing and delivery time depends on, among other things, on availability, payment method, time of order, size of the order and, if applicable, a technical review.

You can find the estimated delivery time for the respective product or at checkout. If there is an unexpected delay, we will inform you personally.

As soon as your order has been shipped, you will receive a shipping confirmation with tracking information by email, if available for the shipping method. You can use this to check the status of your delivery directly with the shipping carrier.

If you cannot find the shipping confirmation, please check your spam folder first. If you have any questions, we will be happy to help you with your order number.

If all items are available, we will ship orders together whenever possible. For large, heavy, bulky, or items with different availability, partial delivery may be advisable or necessary.

If you have placed several separate orders, please contact us as soon as possible with the order numbers. We will then check whether it is still possible to ship them together.

Please inspect the packaging upon delivery if possible. If any damage is visible, document it with photos and note it – if possible – on the delivery receipt or with the courier. If there is severe, clearly visible damage, please do not accept the package without inspecting it if possible.

Then contact us immediately and send us your order number, photos of the package, shipping label, internal packaging, and damaged items. Please keep the packaging and its contents for the time being. We will work with you to resolve the matter. Prompt documentation helps clarify the issue with the shipping service provider.

First, please check the tracking information, your designated delivery location, as well as possible neighbors or pickup points. If the shipment cannot be found despite having a status of "delivered" or has not shown any movement for an extended period, please contact us with your order number.

We will check the shipping status and initiate an investigation with the shipping carrier if necessary. 

You can find the condition directly on the respective product page. Depending on availability, we offer new, used, and refurbished hardware. If no alternative condition such as "used," "refurbished," or any indication of signs of wear is specified on a product page, it is new merchandise.

Used or refurbished products may show visible signs of wear such as light scratches, scuffs, or marks on the casing and ports, depending on the item. However, visible signs of wear do not automatically mean limited functionality: condition and functionality are considered separately.

If any individual item has known peculiarities, more severe cosmetic defects, signs of wear, or missing accessories, we point this out transparently in the product description. For used and refurbished hardware, condition ratings generally refer to appearance, not basic functionality.

At Lunium, refurbished means that the product has already been used or comes from returns or professional IT stock and is inspected before sale. Depending on the product, there may be visible signs of wear.

Refurbished hardware is not automatically the better choice compared to new hardware. However, it can be a sensible alternative if a suitable model is available and offers you a real price advantage. That is why we do not present it as a blanket sustainability promise, but rather as a tested option for customers looking for technically suitable hardware at a fair price.

Yes. Wherever technically and organizationally feasible for the respective item, we perform a functional test before shipping. In addition, we inspect visible areas such as the housing, connectors, contacts, pins, fans, and accessories for any noticeable damage or abnormalities.

The exact inspection depends on the type of product: a power supply, server, switch, or processor cannot always be tested using the same methods. Therefore, we do not promise a comprehensive, all-encompassing test under every conceivable load or in every customer system. What we do guarantee: We conduct responsible inspections and do not sell any goods for which we are aware of any relevant defects.

Not necessarily. The “Scope of delivery” section or the product description is always authoritative. Product images may be for illustrative purposes and show additional accessories, compatible systems, cables, mounts, or decorations that are not necessarily included.

If you are unsure whether a particular accessory is included, please ask us before purchasing. We will be happy to check for you.

Only if expressly stated in the product description or scope of delivery. Especially with server and network hardware, accessories such as power cables, rack rails, transceivers, hard drives, SSDs, SFP modules, licenses, antennas, or mounting materials are not automatically included in the scope of delivery.

If you need a complete, ready-to-use system, please let us know before purchase what you already have and what you need. We will help you identify missing components early on and put together the right combination.

As a consumer, you can cancel your purchase within 14 days of receiving the goods without stating any reasons, unless a statutory exception applies. To exercise your right of cancellation, simply provide a clear statement by email or via the cancellation method provided in our shop.

Please include your order number and the items you wish to return. We will then inform you about the next steps. This FAQ provides a clear summary of the policy; however, the full cancellation policy in the shop always takes precedence. For online purchases, consumers generally have a right of cancellation of at least 14 days.

No. Within the statutory cancellation period, consumers are not required to state a reason. Although brief feedback helps us further improve products, descriptions, and processes, it is voluntary.

If the issue is not a cancellation, but rather a technical problem, shipping damage, or a potentially incorrect item, please write to us in as much detail as possible about what happened. This will help us find the right solution more quickly.

Please contact us before shipping the item so that we can clearly associate the return with your order and provide you with the appropriate return instructions. Pack the item securely for transport and include your order number if possible.

Please use the original packaging or an equally secure alternative whenever possible. Especially with sensitive server, network, and component hardware, protection against impacts, antistatic packaging for sensitive components, and sturdy outer packaging are important.

The cost of a return depends on the reason for the return and the provisions in our cancellation policy. In the case of a standard cancellation, the return costs may generally be borne by the buyer, provided that they have been properly informed.

If an item was delivered incorrectly, arrived damaged during transport, or has a legitimate defect, please contact us before returning it. We will review the case and agree on a fair way to proceed with you.

Yes. As a general rule, the statutory right of withdrawal for consumers also applies to used and refurbished goods, unless a statutory exception applies. Upon return, the goods must show only the wear and tear necessary to inspect their characteristics and functionality.

Please handle and package the hardware with care. If the goods are used beyond what is necessary for inspection or are damaged, a deduction for depreciation may apply. The right of withdrawal and the statutory warranty are different rights: the right of withdrawal allows return within the specified period without giving a reason; the warranty covers defects in the purchased goods.
