Bantam eGPU Enclosure for NVIDIA SFF GPUs

READ THE DESCRIPTION CAREFULLY BEFORE MAKING YOUR PREORDER!
I believe the CButtersTech Bantam eGPU Enclosure is the smallest eGPU enclosure in the world that supports NVIDIA GPUs giving the most performance per volume in an ultra portable and compact size, outperforming all other recent mini eGPUs that use a RX 7600M Xt (mobile gpu). It's also the only mini egpu that can get you NVIDIA DLSS and Frame Generation.

Features:
-Thunderbolt4 eGPU
-85W Power Delivery Support
-Requires LENOVO Thin Tip AC Adapter (options available at checkout)
-Built from durable High Temperature TPU

This enclosure ONLY Compatible with the following eGPUs:

-RTX 4000 Ada Generation SFF (20GB)
-RTX 2000 Ada Generation SFF (16GB)
-RTX A2000 SFF (12GB)

This product is an eGPU enclosure. (GPU not included.)

Current Orders are expected to ship AUG 1.

Q&A

Q: What sort of performance can I expect?
A: It will depend on which GPU you put in the enclosure, but with my own RTX 4000 SFF, and using Surface Pro 10 I have scored a 10755 GPU score in Timespy, 13508 in FFXV benchmark (1080P Standard) far surpassing even the GPD G1 egpu.

Q: What is this Bantam Casing made of?
A: While the casing IS 3D Printed, it is not printed from your common PLA 3D Print Material which would have a potential of melting. The Bantam is dual material printed using TPU and Carbon Fiber PETG. TPU has a softening point of 158C which is a temperature well beyond what the eGPU circuitry will reach. (I.e. It will not melt.)

Q: What GPU can I use with the Bantam?
A: The bantam is custom made to fit a single style of NVIDIA workstation card. Only Nvidia SFF style Cards (that usually operate at 70W) may be used, such as the RTX 4000 Ada Generation SFF 20GB, The RTX 2000 Ada Generation SFF 16GB, The RTX A2000 12GB or other cards that exist in this exact size / shape.

Q: Can I power my notebook at the same time?
A: Yes the Batam has 85W Power Delivery built in on one of the two Thunderbolt USB-C ports, If you use the other USB-C Thunderbolt Port you should power your device with it's own Charger.

Q: What devices have you tested.
A: So far I've only tested on a Surface Pro 10, and the Minisforum V3 Tablet; but I have high expectations it should work on any device that supports Thunderbolt4.

Q: What warranty do you offer?
A: I am more of a hobbyist / tinkerer than a full blown manufacturing company, therefore I only offer a 15 day money-back return policy on the Bantam, and take no liability for any damage that may occur to your GPU, PC or notebook. Use this eGPU at your own risk.

Q: Is there any coil whine?
A: This eGPU is very quiet; having no fans, which makes it mostly as quiet as your GPU you put in it alone, however there is a small amount of coil whine detectable.

Q: Explain the price?
A: This is absolutely not a mass produced product, it is a boutique hand-assembled enthusiast designed enclosure, the initial preorder is only for 10 units to judge demand for this type of product. It's possible that there are only 10 ever built in existence, the thunderbolt chips, circuitry, plastics and ac adapter are all not cheap, nor am I able to achieve volume discounts. The labor, design and assembly is literally being performed by me personally. That said I think I'm offering this thing at a price that is in line with other thunderbolt eGPU enclosures.

Q: What size AC adapter do you recommend?
A: The AC adapter must be a thinkpad style thin plug. If you plan to power both your notebook (up to 85W) power delivery and your GPU (70W) I'd recommend a 170W AC adapter. If you plan on only powering the GPU and not your notebook using the 2nd thunderbolt port, I would use a 90W AC adapter. You can also use SlimQ GAN AC adapters, the 150W and 240W models should do fine.

Q: Why do  you offer the Bantam with and without an AC adapter?
A: There is a lot of different needs and options (see previous question) when it comes down to choosing an AC adapter for this product. I WILL be offering a recommended AC adapter on the store at a very reasonable rate. (Thinkpad 170W AC Adapter - Refurbished) for $40. This adapter will cover all use cases, but you can source your own AC adapter if you think my price for one is unreasonable (It is super reasonable pricing.)
