Outstanding quality and flawless build experience!

I’m extremely happy with my Therhorst DIY i100 Pro Kit. The quality is top-notch – perfectly machined parts, precise fit, and a solid, premium feel. The assembly guide was clear and well-illustrated, making the build smooth and frustration-free.

Everything lined up perfectly, with no adjustments needed, and the end result looks and performs brilliantly. Highly recommended for anyone wanting a high-quality, hassle-free build.

Excellent mod for SFF entheusiasts!

This mod is well worth the money! This kit enables you to put together the cleanest most aestetically pleasing build with god tier components in a small formfactor.

When having questions Jeroen is always eager to help you out! He even made custom 3d drawings for me to help me with the building process. Thanks again Jeroen!

Fantastic Customer Service

Thank you so much for all your fantastic efforts and for bringing my build to the past. I appreciate all the effort and details about the build outside what the manual contains. In all this, whenever I had a question or any kind of clarity in the direction I so desired, he offered up any and every piece of information that helped me get to the landing point.

I pray for nothing but the best in this company!
