I'm interested in sourcing a 2U rack mount PC that meets specific performance criteria. The system should be equipped with a minimum of 16GB of RAM and have an 8-core processor, as it will primarily be used for graphic processing in a broadcast environment. It's crucial that the PC handles demanding tasks efficiently to support our operations. Additionally, please provide information on the components and features that your options come with, such as storage capacity, graphics capabilities, and any potential customization options. I'm looking to place an order for one unit, and since I'm based in the United Kingdom, I'd also appreciate details regarding shipping times and options. Thank you!
