## **1. Planning Your Build**
### **Setting a Budget**
Before buying components, determine your budget. A fast gaming or productivity PC can range from **$800 to $3000+**, depending on performance needs.
– **Budget ($800-$1200):** Mid-range CPU (Intel Core i5 / AMD Ryzen 5), mid-tier GPU (NVIDIA RTX 3060 / AMD RX 6700 XT), 16GB RAM, 1TB SSD.
– **Mid-Range ($1200-$2000):** High-end CPU (Intel i7 / Ryzen 7), powerful GPU (RTX 4070 / RX 7800 XT), 32GB RAM, fast NVMe SSD.
– **High-End ($2000+):** Top-tier CPU (Intel i9 / Ryzen 9), flagship GPU (RTX 4090), 32GB+ RAM, multiple SSDs, liquid cooling.
### **Choosing the Right Components**
Each component affects performance. Prioritize based on your use case:
– **Gaming:** Focus on GPU > CPU > RAM > Fast Storage.
– **Content Creation (Video Editing, 3D Rendering):** CPU > RAM > GPU > High-Capacity Storage.
– **General Productivity:** Balanced CPU, 16GB RAM, SSD for speed.
### **Compatibility Considerations**
– **CPU & Motherboard:** Ensure socket compatibility (e.g., Intel LGA 1700 / AMD AM5).
– **RAM:** Check motherboard support (DDR4/DDR5, speed).
– **GPU & Case:** Verify GPU length fits inside the case.
– **PSU Wattage:** Ensure enough power for all components (use a PSU calculator).

## **4. Step-by-Step Assembly Guide**
### **Step 1: Prepare the Workspace**
– Work on a clean, flat surface.
– Ground yourself to avoid static damage.
### **Step 2: Install the CPU**
1. Open the motherboard socket lever.
2. Align the CPU (match the golden triangle/notch).
3. Gently place it in, then lock the lever.
### **Step 3: Install RAM**
1. Open RAM slots’ clips.
2. Align the notch and press firmly until it clicks.
### **Step 4: Mount the Motherboard**
1. Install I/O shield into the case first.
2. Screw in standoffs (match motherboard holes).
3. Secure the motherboard with screws.
### **Step 5: Install Storage Drives**
– **M.2 SSD:** Insert into the M.2 slot, secure with a screw.
– **SATA SSD/HDD:** Mount in drive bays, connect SATA & power cables.
### **Step 6: Install the Power Supply**
1. Place PSU in its bay (fan facing down if case has a vent).
2. Connect 24-pin (motherboard), 8-pin (CPU), and PCIe (GPU) cables.
### **Step 7: Install the GPU**
1. Remove case PCIe slot covers.
2. Insert GPU into the top PCIe x16 slot, secure with screws.
3. Connect PCIe power cables.
### **Step 8: Cable Management**
– Route cables neatly behind the motherboard tray.
– Use zip ties to secure loose cables.
### **Step 9: Final Checks**
– Ensure all connections are secure.
– Double-check CPU cooler, GPU, and RAM seating.
