Darkflash DS900WD ATX computer case (black) + 4 fansDarkflash DS900WD is an enclosure designed for users who want practical solutions. The tempered glass side panel and wooden front panel provide good visibility of components and give the whole case a distinct look. It allows the installation of motherboards in ATX (Advanced Technology eXtended, a standard motherboard format), M-ATX (Micro Advanced Technology eXtended, a smaller motherboard format) and ITX (Information Technology eXtended, a compact motherboard format) formats, giving you great flexibility when building your computer. With a spacious design and multiple mounting options, it provides convenience in assembling the kit and good air circulation. The kit comes with 4 fans.Various cooling optionsThe DS900WD offers space to install 12 120 mm fans or 2 140 mm fans and water cooling at the top 360 mm or 240 mm, and at the front 240 mm. This allows you to build an effective cooling system for powerful configurations. In addition, the rear panel of the case features a large steel ventilation mesh for effective heat dissipation. As standard, the chassis is equipped with 4 fans to promote air circulation right from installation.Thoughtful layout and ample spaceThe chassis will accommodate a graphics card up to 425 mm in length and CPU cooling up to 170 mm in height. There are seven PCI-E (Peripheral Component Interconnect Express, an interface for expansion cards) slots, allowing the kit to be expanded with additional expansion cards. For storage media, space is provided for two HDDs (Hard Disk Drive, hard drive) or one SSD (Solid State Drive, solid state drive) and one HDD, so you won't run out of space for games and files.Built-in portsThe Darkflash DS900WD chassis is equipped with a set of the most commonly used ports that make everyday use of the computer easier. On the top panel you'll find one USB 3.0 (Universal Serial Bus 3.0, a high-speed data transfer connector), while 2 additional USB 2.0 ports are ideal for connecting a mouse, keyboard, headphones or other accessories. There is also an HD Audio (High Definition Audio, a high-quality audio connector) for convenient connection of headphones and a microphone.Refined detailsOn the right side of the case is a metal mesh that not only provides adequate ventilation, but also blocks larger dust particles from entering the case. What's more, the top and bottom mesh panels also protect your equipment from debris, and their magnetic design makes them easy to install and remove.Durable construction and stylish designThe body of the case is made of 0.5 mm SPCC (Steel, Plate, Cold Rolled, Commercial Quality - structural steel), which ensures high durability. The whole thing measures 470 x 218 x 454 mm and fits into standard under-desk spaces. The stylish design and the ability to illuminate the fans make the set look modern.Included computer case fan x4 user manual Manufacturer Darkflash Model DS900WD ATX Housing type Midi Tower Side panel Tempered glass Motherboard standard ATX / M-ATX / ITX Power supply standard Bottom side, ATX Slots for internal drives 3.5" HDD x2 / 2.5" SSD x2 Expansion card slots 7 Max graphics card length Horizontal mounting: 425 mm Max CPU cooling height 170 mm Max number of fans 12 Fan mounting options Rear: 1x 120 mm; Top: 3x 120 mm / 2x 140 mm; Side: 2x 120 mm; Bottom: 3x 120 mm; Front: x3 120 mm Water cooling mounting options Top: 360 mm / 240 mm; Front: 240 mm Number of fans installed 4 Type of fans INF24T ARGB Buttons and controls Power, Reset Connectors USB 3.0 x1, USB 2.0 x2, HD Audio Material 0.5 mm SPCC Color Black Height 454 mm Width 218 mm Depth 470 mm

FNIRSI 2C23T portable 3-in-1 oscilloscope multimeter signal generatorThe FNIRSI 2C23T is a versatile 3-in-1 measurement tool that combines the functions of a dual-channel oscilloscope, precision multimeter and signal generator. With its compact design, intuitive operation and advanced features, it is an ideal choice for both professional and novice electronics engineers. The built-in 3000 mAh battery provides up to 8 hours of operation, and the 2.8" color screen with a resolution of 320 × 240 px allows for convenient readings in any conditions.Advanced oscilloscope with two channelsThe device offers a dual-channel oscilloscope with a 10 MHz bandwidth and 50 MS/s sampling rate. Each channel operates independently, which eliminates interference and increases measurement precision. Thanks to its well-thought-out hardware architecture (FPGA + ADC + MCU), the FNIRSI 2C23T perfectly reproduces even the finest details of signals. It supports auto, single and normal trigger modes, and allows you to adjust settings automatically - just one click to get a clear graph. You can save waveform snapshots and export them to a computer for easy later analysis.Multimeter with a wide range of applicationsThe multimeter's function allows accurate measurement of voltage (AC up to 750 V, DC up to 1000 V), current, resistance, capacitance, diodes, circuit continuity, as well as zero and phase wire recognition. True RMS measurement and automatic range selection ensure high accuracy and ease of use. Intelligent burnout protection (using ceramic fuses) protects the device and the user. Measurement data can be retained on the screen for easy reading and interpretation.Universal signal generatorThe built-in generator offers seven types of signals, including sine, rectangular, triangle, full-period, half-period, noise and DC. The output frequency ranges from 1 Hz to 2 MHz, and the amplitude from 0.1 to 3.3 V. The user can also adjust the fill factor from 0 to 100%. This is an ideal tool for testing electronic circuits and debugging circuits.Thoughtful design and convenience of useThe FNIRSI 2C23T is made of durable ABS material with an additional silicone cover for drop and shock resistance. The high-grade gold-coated PCB ensures better corrosion resistance and reliable operation. A convenient stand allows stable positioning on a table, and silicone buttons ensure comfortable operation. The USB-C port allows fast charging, and the ultra-thin design (just 3 cm thick) makes the device easy to fit in a bag or backpack.Use in many situationsThe FNIRSI 2C23T will prove useful both in the workshop and in the field. It can measure 220V mains voltage, analyze impulse signals, measure the carrier wave of quartz oscillators, evaluate the voltage ripple of power supplies and test audio signals. Support for five languages (English, Russian, Portuguese, Japanese, German) and software updates ensure the versatility and longevity of the equipment.Included oscilloscope 10X probe probe with crocodile clip probe with multimeter charging cable user manual General Manufacturer FNIRSI Model 2C23T Screen 2.8" HD color Screen resolution 320 x 240 Charging Via Type-C cable (5V/1A) Battery Lithium, 3000 mAh Features Oscilloscope, sound generator, multimeter Standby time 6 hours Supported languages English, Russian, Portuguese, Japanese, German Dimensions 167 x 89 x 35 mm Weight 300 g Oscilloscope Channel Dual channel Sampling frequency 50M Analog bandwidth 10M Memory 32kb Impedance 1MΩ Time base range 50ns-10s Vertical sensitivity 20mV/div-10V/div (X1) Maximum voltage 400 V Trigger mode Automatic, normal, single Trigger type Rising edge, falling edge Display mode YT/scroll Coupling method AC/DC Save waveform screenshots Supported Waveform viewing on computer Supported Sound generator Channel Single Frequency 1Hz-2MHz Amplitude 0.1-3.3V
