It’s in our blood to continuously reassemble and upgrade our precious computers. Unfortunately, we are often constrained by the housing in which our hardware lives. Rest assured. Introducing the Praxis Wetbench. A testbench that blurs the boundary between form and function.

With a slanted motherboard posture the Wetbench sets itself apart from the rest. It’s strength rests within its practical approach. Ease of access to hardware without any obstacles was the core idea. It was fundamental to stay true to a modular open design that provides more freedom to you. But it wouldn’t be like us if we didn’t take it one step further. Not only is this a watercooled friendly testbench that gives absolute freedom to your loops. It will also be introduced into the SX (SpectraX) family. What does that mean? Colors. Colors. And more Colors. Say goodbye to the ordinary, and hello to the new Praxis Wetbench.

Awesome product

I have been wanting a wet bench for years and finally made the decision to get one. I ask myself now, why did I wait so long. Great value for the money . Primo chill shipped my product fast and well packed.

Steve J.

Let me start by saying that I do like the quality of most of the materials, and overall it is a nice bench, but there are a few things that really bothered me with this. My Biggest issue is the radiator mount. Upon mounting the radiator in the bracket and installing it on the bench, the block of an AIO will not reach the CPU and that alone makes this product useless to me. I also have some qualms with how the PSU can only be mounted on the left side/HDD can only be mounted on the right side which is the opposite of the orientation of the SATA ports/power plugs on your motherboard. The instruction booklet says, "These brackets are modular and can be oriented on either side" except the mounting holes on the left and right side are not spaced the same. The material quality overall is great, but the nylon screws are junk. Finally, my instruction booklet has some serious printing issues. I had to find a pdf of the booklet and print my own.

The bottom line - I gave it two stars instead of one solely because I like how sturdy the bench is, but design flaws cripple it's functionality. And after spending $300+ on a product, that is simply unacceptable.

Needs better instructions

Having small dark photos at some key steps and some sort of instructions does not suffice. This is constructed in such a way that sometimes it is counter-intuitive and not having clear instructions and photos that are clearly illustrative throughout and not merely only for the parts list.
Great product though but you have to spend way too much time figuring things out instead of just going ahead and putting it together.

The best casing and delivery so fast

Fast delivery, good item, and five stars shop in here

I went together well, looks very nice. MB is on order.

So far I'd reccomend it for looks and what looks like excellent accessability.

Shipping Carriers

For all domestic and international orders, we rely exclusively on FedEx and USPS as our carriers. Please note that the choice of carrier for flat-rate shipments is not exclusive to either FedEx or USPS. The selection of carrier for your shipment is determined based on the most cost-effective method. APO/PO Boxes are shipped exclusively with USPS.

Transit Times

The transit times displayed during checkout are estimated by the carrier based on the service type and distance and should not be considered a guarantee.

Effective May 2020, FedEx has suspended all transit guarantees and any form of money back for “delivered service failures” (instances where deliveries are not made on time).

Same Day Shipping

We take great pride in our ability to ship out every in-stock order on the same day, as long as it is placed before 2:00pm MST. For orders placed after this time, they will be shipped out on the following business day.

Please be aware that there are some exceptions to this policy, specifically for our SX colored products. These particular colors are custom powder-coated upon order and may necessitate an additional 1-2 business days for the coating process, as well as inspection and packing. We sincerely appreciate your understanding and cooperation in this matter.

Damaged Items

In the event that you receive a damaged package, please ensure to notify us within 48 hours of receipt by contacting our support portal at or email Please refrain from returning the damaged merchandise, as doing so will void any base carrier insurance and prevent us from issuing any credit. It is necessary to retain the damaged package along with its original packaging for a period of five days to facilitate carrier inspection. Kindly keep all packaging and packing materials available for this inspection process.

Shipment Refusal

In the event that a shipped order is refused or returned undelivered, please be aware that there will be certain fees and charges applied to a refund of your order. These include a mandatory 10% restocking fee, a $20.00 Return Service Fee, and the forfeiture of any outbound shipping charges. If the shipment was originally sent with “Free Shipping,” the actual cost of the outbound shipping will be deducted from your refund.

International Policy

Please note that for all international orders, import duties and taxes are applicable and are the responsibility of the recipient. Failure to pay these duties/taxes will result in your package being returned to sender and your order will be subject to the conditions outlined in our “Shipment Refusal Policy.”

Rush Fee

We offer a convenient option called the “Rush Fee” that allows you to bypass the regular order processing queue. By including the “rush fee” with your order, we will promptly prioritize it, ensuring that it is moved to the front of the line for processing. Once received, your order will be automatically printed and will be the very next one to be picked and processed.

It is important to note that selecting the “Rush Fee” option for your order does not guarantee same-day shipping. However, your chances of shipping same day are significantly increased, especially if your order is placed before 2:00pm (MST).

The purpose of the “Rush Fee” is to speed up the processing of your order. It is essential to understand that this fee does not impact the transit time of your order, as that is determined by the shipping service you choose at the time of checkout.

Rush Fees are non-refundable. Once we receive your order, we immediately kick things into high gear and start providing the service, making a refund unnecessary.

Navidium Shipping Protection

We offer the option to add “Shipment Protection” to your order for an extra fee, which serves as insurance for your package. With Navidium’s Shipment Protection, your package is fully covered in the event of damage, theft, or loss during transit. The cost of shipping protection is determined based on the total value of your order prior to adding shipping costs.

To submit a shipping protection claim, please reach out to PrimoChill through our customer support portal at or email The process is straightforward and hassle-free. We will provide you with a saved cart containing the exact items you purchased, and you will need to complete the checkout process to ensure that your shipping information is accurate. The value of the cart will be adjusted to zero, so there will be no charge since you have already selected shipment protection.


Once an order is placed on our e-commerce website, it cannot be canceled/changed or held. This is because our fully automated systems immediately start processing the order, which cannot be stopped or reversed. Therefore, we advise customers to double-check their orders before making a purchase.

Additionally, we would like to emphasize that our e-commerce website ships 98.5% of orders on the same day they are placed by 2:00 pm MST. Allowing cancellations after an order is placed would significantly slow down our shipping process and potentially affect the delivery times for other customers.

We understand that it can be frustrating to be unable to cancel an order, but we ask for your understanding in this matter. By adhering to our cancellation policy, we can ensure that our automated systems and shipping processes continue running smoothly, allowing us to provide fast and efficient service to all our customers.

We understand that sometimes mistakes can happen, and customers may accidentally order the wrong item or change their minds about a purchase. In such cases, we suggest that customers consider our return policy instead.


Our Product Return Policy allows you to initiate a return within 30 days of purchasing a product from The customer is required to cover the costs associated with returning the product. To be eligible for a return, the product must be in its original new packaging and include all accessories and manuals. Because of the substantial discount they receive, B-Stock, clearance, and used/open box products or gift cards cannot be returned.


Kindly be advised that a restocking fee of 15% will be applicable to returned products. However, if sealed boxes or bags have been lost, discarded, scratched, or opened, a higher restocking fee up to 50% will be charged. Furthermore, products that have been mounted, installed, or had any fluid pass through them will incur a restocking fee of 75%. In the event that your order was shipped using the “free shipping” option, the refund issued to you will be reduced by the equivalent amount of the outbound shipping cost.


The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.

Return Inspection

PrimoChill has the right to reject refund requests for any reason in compliance with applicable laws. This policy applies to incomplete items or accessories, as well as hardware, parts, or packaging that have suffered damage. It also covers items misused or used in a way that violates the manufacturer’s recommendations and those damaged or lost during the return process. It is important to securely package the return and ensure it is protected by insurance in case of loss or damage.

Consequently, customers returning such items may be subject to a higher restocking fee in addition to the base fee.
