I've always been a fan of Jonsbo cases, especially their NAS cases and some of their PC cases because of the vertical GPU mounting design.

For the past 13 years, every personal gaming PC I've built has had a vertically mounted GPU, regardless of the case. It all started after my ASUS GTX 760 developed noticeable GPU sag. Ever since then, vertical mounting has become a tradition for all of my builds.

🖥️ Gaming PC

• Intel Core Ultra 7 265K
• ASUS RTX 5070
• G.SKILL Trident Z5 NEO 32GB (2×16GB) DDR5-6400
• Gigabyte B860M AORUS Elite
• CORSAIR RM850e
• 2TB NVMe SSD
• Jonsbo V12

📦 NAS

• Intel Core i7-12700
• 64GB DDR4
• ASUS Prime B760M-A AX D4
• 10GbE NIC
• CORSAIR SF600
• 128GB + 512GB NVMe SSDs
• TrueNAS
• Jonsbo N4

I have a few more Jonsbo PC and NAS builds, but these two definitely look like they belong together.

I recently moved into a temporary apartment, so I couldn't build the custom wooden network rack I originally had in mind. My plan was to make a fully enclosed rack with excellent airflow and large dust filters to keep all my equipment cool while minimizing maintenance

Since I'm limited on time, tools, and materials right now, I put together a simple solution using a metal shelving unit, a metal cabinet, and an exhaust booster fan. I only needed a cutoff tool and a drill to build it.

The setup has two 120mm filtered intake fans at the bottom and the booster exhaust fan pulling the warm air out, creating good airflow throughout the cabinet. So far, everything is staying cool, and the filters are doing a great job keeping dust out. It may not be as nice as the custom rack I wanted, but it's working surprisingly well for a temporary setup

This was cheap and easy to make and can be scaled up or down depending on equipment

Equipment:

Cloud Gateway Fiber

Pro XG 8 PoE

Ugreen NAS DXP6800 Pro

Belink Me mini

Tow U7 Pro XGS

Xfinity XB8

Portable Milwaukee Battery Power Station

I buy a lot of electronics from Facebook Marketplace, so I wanted a reliable way to test them before purchasing to avoid getting scammed. I decided to build a portable power station instead of buying an expensive aftermarket unit.

I built this power station about five years ago, and it is still working flawlessly today.

Specifications

• Maximum Output Power: 1,500 W
• AC Output: 120 VAC
• DC Input: 30–45 VDC
• No-Load Current Draw: 0.2 A
• Efficiency: 85–90% (depending on load)
• Output Frequency: 60 Hz
• Low-Voltage Alarm: 29–31 V
• Low-Voltage Shutdown: 29–30 V

Design

After doing a lot of research, I chose this particular inverter because it already included built-in battery protection features. This saved me from having to design my own low-voltage protection circuitry.

I used a Milwaukee M18 battery adapter, but this project can be adapted to almost any cordless tool battery platform. The important thing is to make sure your battery is protected from over-discharge. If your inverter does not provide this protection, you'll need to add your own battery protection circuit.

I also built a version that uses DeWalt 60V batteries, which is even more efficient.

The inverter already has an internal fuse, so an external fuse is not required. However, you're welcome to add one for additional protection—you can never have too many safety features. I chose to keep the design simple.

Cost Breakdown

• Inverter: $165
• Milwaukee M18 Battery Adapter: $24
• Scrap Wood: $0
• Truck Bed Coating Paint: $8
• Wiring: Included with the inverter

Total Cost: Approximately $200

Tips for Best Performance

For optimal performance and battery life:

• Use batteries with the same amp-hour (Ah) rating.
• Make sure all batteries are charged to the same level before use.
• Use batteries that are similar in age and condition.
• Avoid mixing old and new batteries, as this can reduce performance and potentially damage the batteries over time.
